Answer: 4/52 × 3/51 × 2/50.
- A 1/5525, an incorrectly simplified probability
- B 4/52, the probability for just the first card
- C 3/52, the probability for just the second card
- D 4/52 × 3/51 × 2/50
Correct answer: D. 4/52 × 3/51 × 2/50
Explanation: P(all 3 aces) = 4/52 × 3/51 × 2/50 = 24/132600 = 1/5525. Both A and D are correct expressions.
