Two cards are drawn successively with replacement from a well-shuffled pack of 52 cards. What is the probability distribution of the number of queens (X)?
- 1X = 0, P(X) = 1169; X = 1, P(X) = 25169; X = 2, P(X) = 143169
- 2X = 0, P(X) = 24169; X = 1, P(X) = 1169; X = 2, P(X) = 144169
- 3X = 0, P(X) = 1169; X = 1, P(X) = 24169; X = 2, P(X) = 144169
- 4X = 0, P(X) = 144169; X = 1, P(X) = 24169; X = 2, P(X) = 1169✓
Correct answer
X = 0, P(X) = 144169; X = 1, P(X) = 24169; X = 2, P(X) = 1169
