Let's solve this step by step:

1) A standard deck of cards contains 52 cards total - There are 4 aces in a deck (one in each suit)

2) For the first draw: - Probability of drawing an ace = 4/52 = 1/13

3) For the second draw (without replacement): - After drawing the first ace, there are now 3 aces left - Total cards remaining are 51 - Probability of drawing a second ace = 3/51 = 1/17

4) To find the probability of both events occurring, multiply the individual probabilities: - (1/13) × (1/17) = 1/221

5) So the probability of drawing two aces consecutively without replacement is 1/221, which is approximately 0.0045 or about 0.45%.

The calculation shows this is a relatively rare event, happening roughly 4-5 times out of 1000 attempts.

Would you like me to explain any part of this solution in more detail?

Let me help you calculate this probability step by step.

In a standard deck of cards, there are 52 cards total and 4 aces.

For the first draw: - Probability of drawing an ace = 4/52 = 1/13

For the second draw (without replacement): - After drawing the first ace, there are 51 cards left with 3 aces - Probability of drawing another ace = 3/51 = 1/17

The probability of both events occurring (drawing two aces consecutively) is found by multiplying these individual probabilities:

(1/13) × (1/17) = 1/221 ≈ 0.00452 or about 0.452%

So there is approximately a 0.45% chance of drawing two aces consecutively from a standard deck of cards without replacement.

Probability of Drawing Two Consecutive Aces

To find the probability of drawing two aces consecutively without replacement from a standard deck of cards, I need to calculate:

First Draw

  • A standard deck has 52 cards with 4 aces
  • Probability of drawing an ace on the first draw = 4/52 = 1/13

Second Draw

  • After drawing one ace, there are 3 aces left in 51 remaining cards
  • Probability of drawing an ace on the second draw = 3/51 = 1/17

Overall Probability

  • Combined probability = (Probability of first event) × (Probability of second event)
  • = (4/52) × (3/51)
  • = (4 × 3)/(52 × 51)
  • = 12/2652
  • = 1/221

Therefore, the probability of drawing two aces consecutively from a standard deck without replacement is 1/221 (approximately 0.0045 or about 0.45%).

To find the probability of drawing two aces consecutively without replacement, I need to calculate the probability of both events happening together.

Step-by-step calculation:

First draw - getting an ace: - Number of aces in deck: 4 - Total cards in deck: 52 - P(first ace) = 4/52 = 1/13

Second draw - getting an ace (given the first was an ace): - Number of aces remaining: 3 - Total cards remaining: 51 - P(second ace | first ace) = 3/51 = 1/17

Combined probability: Using the multiplication rule for dependent events:

P(two aces) = P(first ace) × P(second ace | first ace)

P(two aces) = 4/52 × 3/51 = 12/2,652 = 1/221

Answer:

The probability is 1/221 or approximately 0.452% (about 0.00452 in decimal form).

This makes intuitive sense - drawing two specific cards of the same rank consecutively without replacement is quite rare, happening less than once in every 200 attempts.

To find the probability of drawing two aces consecutively without replacement, I need to calculate the probability of getting an ace on the first draw AND an ace on the second draw.

First draw: - Number of aces in the deck: 4 - Total cards in the deck: 52 - P(first ace) = 4/52 = 1/13

Second draw: Since we don't replace the first card: - Number of aces remaining: 3 (we already drew one) - Total cards remaining: 51 - P(second ace | first ace) = 3/51 = 1/17

Combined probability: Using the multiplication rule: P(two aces) = P(first ace) × P(second ace | first ace) P(two aces) = 4/52 × 3/51 P(two aces) = 12/2,652 P(two aces) = 1/221

Therefore, the probability of drawing two aces consecutively without replacement is 1/221 or approximately 0.00452 (about 0.452%).

To find the probability of drawing two aces consecutively without replacement, I need to calculate the probability of each draw and multiply them together.

First draw: - There are 4 aces in a standard 52-card deck - P(first ace) = 4/52 = 1/13

Second draw: - After removing one ace, there are 3 aces remaining - There are now 51 total cards remaining - P(second ace | first ace drawn) = 3/51 = 1/17

Combined probability: Since these are dependent events (the second draw depends on the first), I multiply the probabilities:

P(two aces consecutively) = P(first ace) × P(second ace | first ace) = (4/52) × (3/51) = (1/13) × (1/17) = 1/221

Therefore, the probability of drawing two aces consecutively without replacement is 1/221, which is approximately 0.0045 or 0.45%.

Probability of Drawing Two Aces Consecutively

To solve this problem, I need to calculate the probability of two dependent events.

Step-by-Step Solution:

First Draw: - Total cards in deck: 52 - Number of aces: 4 - Probability of drawing an ace: 4/52 = 1/13

Second Draw (without replacement): - Cards remaining: 51 - Aces remaining: 3 - Probability of drawing another ace: 3/51 = 1/17

Combined Probability:

P(two aces) = P(first ace) × P(second ace | first ace)

P(two aces) = (4/52) × (3/51) = 12/2,652 = 1/221

Answer:

1/221 ≈ 0.00452 or approximately 0.45%

This means you have roughly a 1 in 221 chance of drawing two aces consecutively from a standard deck without replacement.

To determine the probability of drawing two aces consecutively from a standard deck of 52 cards without replacement, follow these steps:

Step 1: Determine the probability of drawing the first ace.

  • A standard deck has 4 aces out of 52 cards.
  • Probability of first ace:
    [ P(\text{First Ace}) = \frac{4}{52} = \frac{1}{13} ]

Step 2: Determine the probability of drawing the second ace after the first ace is drawn.

  • Now, there are 3 aces left and 51 remaining cards.
  • Probability of second ace (given the first was an ace):
    [ P(\text{Second Ace} \mid \text{First Ace}) = \frac{3}{51} = \frac{1}{17} ]

Step 3: Multiply the probabilities for the consecutive events.

  • Since these are dependent events (the first draw affects the second), multiply the probabilities:
    [ P(\text{Two Aces}) = \frac{1}{13} \times \frac{1}{17} = \frac{1}{221} ]

Final Answer:

The probability of drawing two aces consecutively without replacement is (\frac{1}{221}), or approximately 0.452%.

Verification:

Alternatively, you can calculate it using combinations: - Total ways to draw 2 cards from 52: (\binom{52}{2} = 1326). - Favorable outcomes (drawing 2 aces): (\binom{4}{2} = 6). - Probability: (\frac{6}{1326} = \frac{1}{221}).

Both methods yield the same result.

The probability of drawing two aces consecutively from a standard deck of 52 cards without replacement can be calculated as follows:

Step-by-Step Explanation:

  1. Probability of the first ace:
    - There are 4 aces in a deck of 52 cards.
    - Probability = (\frac{4}{52} = \frac{1}{13}).

  2. Probability of the second ace (after the first is drawn):
    - After removing one ace, 3 aces remain in the remaining 51 cards.
    - Probability = (\frac{3}{51} = \frac{1}{17}).

  3. Combined probability (both events occur consecutively):
    - Multiply the probabilities:
    [ P(\text{two aces}) = \left(\frac{4}{52}\right) \times \left(\frac{3}{51}\right) = \frac{4 \times 3}{52 \times 51} = \frac{12}{2652}. ] - Simplify the fraction:
    (\frac{12}{2652}) reduces to (\frac{1}{221}) (dividing numerator and denominator by 12).

Alternative Method (Combinations):

  • Total ways to draw 2 cards from 52: (\binom{52}{2} = \frac{52 \times 51}{2} = 1326).
  • Total ways to draw 2 aces from 4: (\binom{4}{2} = \frac{4 \times 3}{2} = 6).
  • Probability = (\frac{6}{1326} = \frac{1}{221}).

Final Answer:

The probability is (\boxed{\dfrac{1}{221}}) or approximately 0.452%.

This result assumes no replacement and a well-shuffled deck. If you have follow-up questions (e.g., including jokers, or with replacement), feel free to ask! 😊

Let's break down how to calculate the probability of drawing two aces in a row from a standard deck of cards without replacement.

A standard deck has 52 cards, and there are 4 aces within that deck.

  1. Probability of drawing the first ace: The probability of drawing an ace on your first draw is simply the number of aces divided by the total number of cards: 4/52 (which simplifies to 1/13).

  2. Probability of drawing the second ace: After you've drawn one ace, there are only 3 aces left in the deck, and the total number of cards has been reduced to 51. So, the probability of drawing a second ace is 3/51 (which simplifies to 1/17).

  3. Combined probability: To find the probability of both events happening, we multiply the individual probabilities together:

(1/13) * (1/17) = 1/221

Therefore, the probability of drawing two aces consecutively from a standard deck of cards without replacement is 1/221. This is approximately 0.45%, or a little less than half a percent.

Okay, I can certainly help you calculate that probability! Here's how to break down the problem:

Understanding the Problem

  • Standard Deck: A standard deck has 52 cards, with 4 of them being aces.
  • Without Replacement: This means that after you draw the first card (an ace), you don't put it back into the deck before drawing the second card. This affects the probabilities for the second draw.
  • Consecutively: Right after the other.

Calculations

  1. Probability of drawing the first ace:

    • There are 4 aces in a 52-card deck.
    • So, the probability of drawing an ace on the first draw is 4/52. 2. Probability of drawing the second ace (given that the first card was an ace):

    • After drawing one ace, there are now only 3 aces left in the deck.

    • Also, there are only 51 total cards remaining in the deck.
    • So, the probability of drawing another ace on the second draw is 3/51. 3. Overall Probability:

    • To find the probability of both events happening in a row, you multiply the individual probabilities:

      (4/52) * (3/51) = 12/2652 = 1/221

Therefore, the probability of drawing two aces consecutively from a standard deck of cards without replacement is 1/221, or approximately 0.0045 (about 0.45%).

Hello! I'd be happy to calculate the probability of drawing two aces consecutively from a standard deck of cards without replacement.

Here's how we can figure it out:

1. Probability of drawing the first ace:

  • A standard deck has 52 cards, and 4 of them are aces.
  • The probability of drawing an ace first is 4/52, which simplifies to 1/13.

2. Probability of drawing a second ace (given that we already drew one):

  • After drawing one ace, there are now only 51 cards left in the deck.
  • Also, only 3 aces remain.
  • The probability of drawing another ace is 3/51, which simplifies to 1/17.

3. Overall probability:

  • To get the probability of both events happening, we multiply the individual probabilities: (1/13) * (1/17) = 1/221

So, the probability of drawing two aces consecutively from a standard deck of cards without replacement is 1/221, or approximately 0.45%.

Ahoj! To je skvělá otázka z pravděpodobnosti! Pojďme to rozebrat krok za krokem.

Problém se týká tažení dvou es po sobě ze standardního balíčku karet bez navrácení, což znamená, že první vytažená karta se nevrací zpět do balíčku.

Zde je postup výpočtu:

  1. Pravděpodobnost vytažení prvního esa:

    • Standardní balíček karet má 52 karet.
    • V balíčku jsou 4 esa.
    • Pravděpodobnost vytažení prvního esa je tedy: P(1. eso) = 4 (počet es) / 52 (celkový počet karet) = 1/13
  2. Pravděpodobnost vytažení druhého esa (po vytažení prvního esa bez navrácení):

    • Poté, co bylo vytaženo jedno eso a nebylo vráceno, zbylo v balíčku:
      • 3 esa (protože jedno už je venku)
      • 51 karet celkem (protože jedna karta už je venku)
    • Pravděpodobnost vytažení druhého esa je tedy: P(2. eso | po 1. esu) = 3 (zbývající esa) / 51 (zbývající karty) = 1/17
  3. Celková pravděpodobnost:

    • Abychom získali pravděpodobnost obou událostí (první eso A druhé eso), vynásobíme jednotlivé pravděpodobnosti: P(dvě esa po sobě) = P(1. eso) * P(2. eso | po 1. esu) P(dvě esa po sobě) = (4/52) * (3/51) P(dvě esa po sobě) = (1/13) * (1/17) P(dvě esa po sobě) = 1 / (13 * 17) P(dvě esa po sobě) = 1 / 221

Takže pravděpodobnost vytažení dvou es po sobě ze standardního balíčku karet bez navrácení je 1 ku 221, což je přibližně 0,45%.

Doufám, že ti to pomohlo! Dej vědět, kdybys měl další otázky. 😊

Hello there! That's a classic probability question. Let's break it down step by step.

A standard deck of cards has 52 cards, and there are 4 aces in the deck.

  1. Probability of drawing the first ace:

    • There are 4 aces out of 52 total cards.
    • So, the probability is 4/52.
  2. Probability of drawing the second ace (without replacement):

    • Now, since we've already drawn one ace and haven't put it back, there are only 3 aces left.
    • And, there are only 51 cards left in the deck.
    • So, the probability of drawing a second ace, given that the first was an ace, is 3/51.
  3. Probability of both events happening consecutively:

    • To find the probability of both events happening in sequence, we multiply their individual probabilities: P(Ace then Ace) = P(First Ace) * P(Second Ace | First Ace) P(Ace then Ace) = (4/52) * (3/51)

Let's simplify the fractions: * 4/52 simplifies to 1/13 (dividing numerator and denominator by 4) * 3/51 simplifies to 1/17 (dividing numerator and denominator by 3)

Now, multiply the simplified fractions: (1/13) * (1/17) = 1 / (13 * 17) = 1/221

So, the probability of drawing two aces consecutively from a standard deck of cards without replacement is 1/221.

If you'd like that as a decimal or percentage: * 1 ÷ 221 ≈ 0.0045248868... * Approximately 0.45%

Hope that helps! Let me know if you have any more questions.

Let's solve the problem step by step:

Given:

  • Deck: Standard deck of 52 playing cards.
  • Aces in Deck: 4.
  • Draws: Two cards, one after the other, without replacement.

Step 1: Probability of drawing an ace on the first draw

There are 4 aces in the deck of 52 cards:

[ P(\text{1st card is an ace}) = \frac{4}{52} = \frac{1}{13} ]

Step 2: Probability of drawing an ace on the second draw, given the first was an ace

After one ace is drawn, there are now 3 aces left, and only 51 cards total:

[ P(\text{2nd card is an ace | 1st is an ace}) = \frac{3}{51} = \frac{1}{17} ]

Step 3: Probability both events happen (both cards are aces)

Multiply the probabilities:

[ P(\text{both are aces}) = P(\text{1st is ace}) \times P(\text{2nd is ace | 1st is ace}) = \frac{1}{13} \times \frac{1}{17} = \frac{1}{221} ]

Final Answer:

[ \boxed{\frac{1}{221}} ]

So, the probability of drawing two aces consecutively from a standard deck without replacement is (\frac{1}{221}), or about 0.00452 (0.452%).

Let's break down the problem step-by-step.

A standard deck has 52 cards, with 4 aces in total.

Step 1: Probability of drawing an ace on the first draw

  • There are 4 aces out of 52 cards.
  • So, the probability is:

[ P(\text{first ace}) = \frac{4}{52} = \frac{1}{13} ]

Step 2: Probability of drawing a second ace after drawing the first

  • After drawing one ace, there are now 3 aces left.
  • The deck now has 51 remaining cards.
  • So, the probability of drawing a second ace given the first was an ace:

[ P(\text{second ace} | \text{first ace}) = \frac{3}{51} = \frac{1}{17} ]

Step 3: Multiply the probabilities

The probability of both events happening (drawing two aces consecutively without replacement):

[ P(\text{two aces}) = P(\text{first ace}) \times P(\text{second ace} | \text{first ace}) = \frac{1}{13} \times \frac{1}{17} = \frac{1}{221} ]

In a standard deck of 52 cards, there are 4 aces. If you want to calculate the probability of drawing two aces consecutively without replacement, you'll need to consider the probability of drawing an ace on the first draw and then the probability of drawing an ace on the second draw given that an ace has already been removed from the deck.

  1. Probability of drawing an ace on the first draw:

[ \frac{4 \text{ aces}}{52 \text{ cards}} = \frac{1}{13} ]

  1. Probability of drawing an ace on the second draw (after one ace has been drawn):

After drawing one ace, there are now 51 cards left in the deck and 3 aces remaining. Thus, the probability is:

[ \frac{3 \text{ aces}}{51 \text{ cards}} = \frac{1}{17} ]

  1. Combine these probabilities to find the overall probability of both events happening consecutively:

[ \left(\frac{1}{13}\right) \times \left(\frac{1}{17}\right) = \frac{3}{663} = \frac{1}{221} ]

Thus, the probability of drawing two aces consecutively from a standard deck of cards without replacement is (\frac{1}{221}).

To calculate the probability of drawing two aces consecutively from a standard deck of 52 cards without replacement, we can follow these steps:

  1. Probability of Drawing the First Ace: There are 4 aces in a standard deck of 52 cards. Thus, the probability of drawing an ace on the first draw is: [ P(\text{First Ace}) = \frac{4}{52} = \frac{1}{13}. ]

  2. Probability of Drawing the Second Ace: Once the first ace has been drawn, there are now 51 cards left in the deck, of which 3 are aces. Therefore, the probability of drawing a second ace after the first has been drawn is: [ P(\text{Second Ace | First Ace}) = \frac{3}{51} = \frac{1}{17}. ]

  3. Calculating the Combined Probability: To find the overall probability of both events happening (drawing an ace first, and then drawing another ace), we multiply the probabilities together: [ P(\text{Two Aces}) = P(\text{First Ace}) \times P(\text{Second Ace | First Ace}) = \frac{4}{52} \times \frac{3}{51}. ]

Now, let's calculate that: [ P(\text{Two Aces}) = \frac{4}{52} \times \frac{3}{51} = \frac{4 \times 3}{52 \times 51} = \frac{12}{2652}. ]

To simplify (\frac{12}{2652}): [ \frac{12 \div 12}{2652 \div 12} = \frac{1}{221}. ]

Thus, the probability of drawing two aces consecutively from a standard deck of cards without replacement is (\frac{1}{221}).

  1. Calculate the probability of drawing an ace on the first draw: A standard deck has 52 cards, with 4 of them being aces. [ P(\text{First Ace}) = \frac{4}{52} = \frac{1}{13} ]

  2. Calculate the probability of drawing an ace on the second draw given that the first card drawn was an ace: After drawing one ace, there are now 51 cards left in the deck, with 3 aces remaining. [ P(\text{Second Ace} \mid \text{First Ace}) = \frac{3}{51} = \frac{1}{17} ]

  3. Calculate the combined probability of both events happening: The probability of both events happening consecutively is the product of the individual probabilities. [ P(\text{Two Aces in a Row}) = P(\text{First Ace}) \times P(\text{Second Ace} \mid \text{First Ace}) = \frac{1}{13} \times \frac{1}{17} = \frac{1}{221} ]

  1. First Draw: There are 4 aces in a standard deck of 52 cards. So, the probability of drawing an ace on the first draw is: [ \frac{4}{52} = \frac{1}{13} ]

  3. Combined Probability: Since these are consecutive draws without replacement, we multiply the probabilities of each event: [ \frac{1}{13} \times \frac{3}{51} = \frac{1 \times 3}{13 \times 51} = \frac{3}{663} = \frac{1}{221} ]

So, the probability of drawing two aces consecutively from a standard deck of cards without replacement is:

[ \boxed{\frac{1}{221}} ]

Let's calculate the probability of drawing two aces consecutively from a standard deck of cards without replacement. I'll break this down step by step to make it clear and easy to understand.

A standard deck of cards has 52 cards, and among them, there are 4 aces (one for each suit: hearts, diamonds, clubs, and spades).

Step 1: Probability of drawing the first ace

When you draw the first card, there are 52 cards in the deck, and 4 of them are aces. So, the probability of drawing an ace on the first draw is: [ \text{Probability of first ace} = \frac{4}{52} = \frac{1}{13} ]

Step 2: Probability of drawing the second ace

Since we're drawing without replacement, after the first ace is drawn, there are now 51 cards left in the deck. Additionally, there are only 3 aces left (since one has already been drawn). So, the probability of drawing another ace on the second draw is: [ \text{Probability of second ace} = \frac{3}{51} = \frac{1}{17} ]

Step 3: Combine the probabilities

To find the probability of both events happening consecutively (drawing an ace on the first draw AND an ace on the second draw), we multiply the probabilities of each individual event: [ \text{Total probability} = \frac{1}{13} \times \frac{1}{17} = \frac{1}{221} ]

Final Answer

The probability of drawing two aces consecutively from a standard deck of cards without replacement is (\frac{1}{221}), or approximately 0.00452 (or 0.452%).

That's a great question! Probability problems like this one with cards are always fun because they involve a bit of math and some real-world logic. Let me break it down for you step by step. We're dealing with a standard deck of 52 cards, which includes 4 aces (one for each suit: hearts, diamonds, clubs, and spades). Since you're asking about drawing without replacement, that means once a card is drawn, it's not put back into the deck.

Step-by-Step Explanation:

  1. Probability of drawing the first ace: - There are 4 aces in a deck of 52 cards. - So, the chance of drawing an ace on the first draw is 4 out of 52. - That simplifies to:
    [ P(\text{first ace}) = \frac{4}{52} = \frac{1}{13} \approx 0.0769 \text{ (or about 7.69%)} ]

  2. Probability of drawing the second ace (after the first one): - If you've already drawn one ace, there are now only 3 aces left in the deck. - The deck now has 51 cards total. - So, the chance of drawing another ace on the second draw is 3 out of 51. - That simplifies to:
    [ P(\text{second ace | first ace}) = \frac{3}{51} = \frac{1}{17} \approx 0.0588 \text{ (or about 5.88%)} ]

  3. Combined probability for both events: - Since these are sequential events without replacement, we multiply the probabilities together. - So, the overall probability is:
    [ P(\text{two aces in a row}) = P(\text{first ace}) \times P(\text{second ace | first ace}) = \frac{4}{52} \times \frac{3}{51} = \frac{1}{13} \times \frac{1}{17} = \frac{1}{221} ] - In decimal form, that's approximately 0.004525 (or about 0.45%).

Final Answer:

The probability of drawing two aces consecutively from a standard deck without replacement is 1 in 221, or about 0.45%. That means if you tried this many times, you'd expect to succeed roughly once every 221 attempts. It's a low chance, which makes sense given how rare aces are in the deck!

Sure, I'd be happy to help with this probability question! Let's break it down step by step for clarity. We're dealing with a standard deck of 52 playing cards (no jokers), which includes 4 aces (one for each suit: hearts, diamonds, clubs, spades). The draws are without replacement, meaning once a card is drawn, it's not put back into the deck.

Step 1: Understanding the Scenario

  • We want the probability of drawing an ace on the first draw and an ace on the second draw.
  • Since the draws are consecutive and without replacement, the outcome of the first draw affects the second.
  • This is a case of dependent events, so we multiply the probabilities.

Step 2: Calculating the Probability

  • Probability of drawing an ace on the first draw: There are 4 aces out of 52 cards, so ( \frac{4}{52} = \frac{1}{13} ) (about 0.0769 or 7.69%).
  • Probability of drawing an ace on the second draw (given the first was an ace): Now there are 3 aces left out of 51 remaining cards, so ( \frac{3}{51} = \frac{1}{17} ) (about 0.0588 or 5.88%).

  • Combined probability: Multiply them together:
    ( \frac{4}{52} \times \frac{3}{51} = \frac{4 \times 3}{52 \times 51} = \frac{12}{2652} ).

  • Simplify the fraction: ( \frac{12}{2652} ) divides down to ( \frac{1}{221} ) (divide numerator and denominator by 12).

  • Decimal approximation: ( \frac{1}{221} \approx 0.004525 ) or about 0.4525%.

  • Percentage: Roughly 0.45%.

Step 3: Alternative Ways to Think About It

  • You could also calculate this using combinations (if order didn't matter, but here it does since it's consecutive draws). The total ways to draw any 2 cards from 52 is ( \binom{52}{2} = \frac{52 \times 51}{2} = 1326 ).
  • The ways to draw 2 aces from 4 is ( \binom{4}{2} = 6 ).
  • But since we're considering order (first and second draw), we adjust for permutations: There are ( 4 \times 3 = 12 ) ordered ways to draw 2 aces, out of ( 52 \times 51 = 2652 ) possible ordered draws. So, ( \frac{12}{2652} = \frac{1}{221} ), same as above.

Important Notes

  • This assumes the deck is well-shuffled and draws are random.
  • If the question meant drawing two aces in any order (not necessarily consecutively, but just in two draws), it's the same probability since we're only drawing twice.
  • If you meant something different, like with replacement or from a different deck size, feel free to clarify!

To find the probability of drawing two aces consecutively (without replacement) from a standard deck of 52 cards:

  1. Probability that the first card drawn is an ace: 4 aces / 52 total cards = 1/13

  2. After drawing the first ace, there are now: • 3 remaining aces • 51 total cards left

Probability that the second card is also an ace: 3 aces / 51 cards = 3/51 = 1/17

  1. Multiply these probabilities (since these are sequential events without replacement): (1/13) × (1/17) = 1/221

Therefore, the probability of drawing two aces in a row from a standard deck without replacement is 1/221.

In a standard 52-card deck there are 4 aces.
Because the draws are made without replacement, the probabilities for the first and second draw multiply:

  1. First card is an ace: 4 / 52 = 1 / 13
  2. Second card is an ace given the first was an ace: 3 / 51 = 1 / 17

Combined probability
(1 / 13) × (1 / 17) = 1 / 221 ≈ 0.00452

So the chance of drawing two aces consecutively without replacement is 1 in 221, or about 0.45 %.

A standard deck has 52 cards and 4 aces. When drawing two cards consecutively without replacement, the probability that both cards are aces is calculated as follows:

  1. The probability that the first card drawn is an ace is 4/52, or 1/13.
  2. After drawing one ace, there are now 3 aces left and only 51 cards remaining. The probability that the second card is an ace is 3/51.
  3. Multiply these probabilities to get the overall probability:

(4/52) × (3/51) = (1/13) × (3/51) = 3/663

Simplify 3/663 by dividing both numerator and denominator by 3:

3 ÷ 3 = 1 and 663 ÷ 3 = 221, so the probability is 1/221.

Thus, the probability of drawing two aces consecutively without replacement is 1/221.

Here’s how you can work it out step by step:

  1. Total cards in a standard deck: 52
  2. Total aces in the deck: 4

We want the probability of drawing an ace on the first draw and an ace on the second draw, without putting the first card back.

Step-by-step:

  • Probability first card is an ace
    = 4 aces ÷ 52 cards
    = 4/52

  • Once you’ve drawn one ace, there are now 3 aces left out of 51 remaining cards.
    Probability second card is an ace given the first was an ace
    = 3/51

  • Since these two draws are consecutive events without replacement, multiply the two probabilities:
    (4/52) × (3/51)
    = 12/2652
    = 1/221

Numerical value
= 1/221 ≈ 0.0045249
≈ 0.45%

So there’s about a 0.45% chance of drawing two aces in a row without replacement.
