I'm playing 5 card poker with my friend and I'm dealt J of clovers, hearts and spades, with a 5 of diamonds and an 8 of clovers. I'm trying the find the number of ways my friend could get a two pair (in a 5 card hand) given that he receives different cards as me. I've tried different combinations and cases with the poker formula for two pair and I know the answer is 77949. I just don't know how.
