After one-pair, the next most common hands are two-pair and three-of-a-kind: Two-pair: Two cards have one rank, two cards have another rank, and the remaining card has a third rank. e.g. {2♥, 2♠, 5♥, 5♣, K♦} Three-of-a-kind: Three cards have one rank and the remaining two cards have two other ranks. e.g. {2♥, 2♠, 2♣, 5♣, K♦} Calculate the probability of each type of hand.
