Math Problem Statement
Solution
To solve this problem, we need to find the probability of drawing two queens in succession without replacement from a standard deck of 52 cards.
Step-by-Step Solution:
-
First card (drawing a queen):
- There are 4 queens in a deck of 52 cards.
- The probability of drawing a queen on the first draw is:
-
Second card (drawing a queen after the first):
- After drawing the first queen, there are now 3 queens left and only 51 cards remaining.
- The probability of drawing a second queen is:
-
Total probability: Since these events are dependent (without replacement), we multiply the probabilities of the two events:
Thus, the probability of drawing two queens successively is .

Here are 5 related questions to think about:
- What is the probability of drawing two aces successively from a deck of 52 cards?
- How would the probability change if the cards were drawn with replacement?
- What is the probability of drawing a queen and then a king successively?
- What is the probability of drawing no face cards (king, queen, jack) in two draws?
- How does the probability change if you are drawing 3 queens instead of 2?
Tip: In probability problems involving "without replacement," remember to adjust both the number of favorable outcomes and the total outcomes after each draw.

P(first queen) = 4/52 = 1/13
P(second queen after first) = 3/51 = 1/17
P(two queens) = P(first queen) * P(second queen) = 1/13 * 1/17 = 1/221
