I have a HW problem I'm trying to pin down and I think I'm confusing myself...
Question: In a card game w/ a standard 52 card deck, a hand is a set of 3 cards. Count the # of hands that are...
a) Jack,Queen,King of 3 different suits
b) 3 Aces of different suits
c) Jack,Queen,King of 2 different suits
My thoughts...
a) $ {13 \choose 3}{4 \choose 3}$ 1st is for the J,Q,K and 2nd for the suits?
b)${4 \choose 3}$ 4 possible aces, choosing 3?
c) ${13 \choose 3}{4 \choose 2}$ 1st is for the J,Q,K and 2nd for the suits?
I've been staring at it for too long to make anymore sense of it. Anyone know the answer and maybe some guidance? Thanks!
