Poker

Look at pair. Let's label Spades as A, Clubs as B, Hearts as C, and Diamonds as D.

Let's look at a single card, let's look at 9.

9A and 9B is a pair, 9A and 9C is a pair, 9A and 9D is a pair, 9B and 9C is a pair, 9B and 9D are a pair, and 9C and 9D are a pair. Six distinct sets that are possible involving 9.

Now that is for one number, we have 13 numbers (2-10 + A + K + Q + J). So multiply our 6 sets x 13 different cards = 78 different possible hands for a pair.

That's not really statistics.

That's only 78 different combinations of a pair, not the hands with the pair.
