Five of a kind is a hand that contains five cards of one rank, such as five threes. It ranks above a straight flush but is only possible when using one or more wild cards, as there are only four cards of each rank in the deck. So the answer is 0 if you're not using any wild cards. If you're using wild cards, the answer would be different for different numbers of wild cards, and whether jokers are being used as wild cards. Edwin
