Three-card hand probability of a flush (any same suit):
A1/4
B4 × C(13,3)/C(52,3) = 4 × 286/22100 = 0.0518
C1/13
D1/52
Answer & Solution
Correct answer: B. 4 × C(13,3)/C(52,3) = 4 × 286/22100 = 0.0518
Suits: 4 choices. Flush: 3 cards same suit: C(13,3) = 286. Total: C(52,3) = 22100. P = 4 × 286/22100 = 1144/22100 ≈ 0.0518.
