The number of such hands is (13-choose-1)*(4-choose-2)*(12-choose-3)*[(4-choose-1)]^3.If all hands are equally likely,the probability of a single pair is obtained by dividing by (52-choose-5).This probability is 0.422569.
即
13c1 * 4c2 * 12c3 * 4e3 / 52c5 = 0.422569
c:组合

先选一对:
13c1,在13张牌点中任选一个点
4c2,四种花色任选两种.
再选三张不重复的牌
12c3,剩下的三张牌点从12中选三个不同的点.
4*3,每个点都可以有四种不同花色
最后除以总的牌的可能组合
52c5
