✔ 最佳答案
There are 13 choices for the value of the triple.There are 12 choices for the value of the pair.
For colour: There are: C(4,3) = 4 ways to get the triple and there are: C(4,2) = 6 ways to get the pair.
Therefore, there are : 13 12 4 6 = 3,744 possible Full Houses.
The probability of being dealt a full house
P(Full House) = 3,744 / 2,598,960 = 78 / 54,145 = 0.00144057623
