Question 1126830: Suppose you have a deck of 52 playing cards (no jokers)
A. How many five-card hands containing exactly three aces are possible?
B. How many five-card hands containing exactly three of a kind are possible?
Answer by math_helper(2461) (Show Source):
You can put this solution on YOUR website! A. C(4,3)*C(48,2) = 
B. C(4,3)*C(48,2)*C(13,1) = 
As "three of a kind" is a specific type of poker hand, I should mention this answer includes full-houses (where the non-triplicate cards match in rank).
To exclude full-houses, note that there are C(13,1)*C(4,3)*C(12,1)*C(4,2) = 3744 of them, so you would have 58656-3744 true "three of kind" poker hands.
