How many 5 card hands contain exactly 2 queens

There are 4 queens in the deck, hence (4 choose 2) = 4!/(2! (4-2)!) = 6 ways of getting 2 queens.

The other 3 cards in the deck can be any of the remaining 48 non-queens; there are (48 choose 3) = 48!/(3! (48-3)!) = 17,296 ways of getting these.

In total, there are (4 choose 2)*(48 choose 3) = 103,776 total possible hands.

one set of data has more variation than the other. hope this !
