Permutations and combinations?
From a standard 52 card deck find how many 5 card hands are possible that have

a. 3 hearts and 2 clubs

b. 1 ace, 2 jacks, and 2 kings

I am kind of stuck on where to start I think it is a combination since order does not matter but I am not sure how to get (n,r) I mean I think n would be the 52 but I am not sure?(Crying)

There are 13 $\heartsuit$'s choose 3 of them and 13 $\clubsuit$'s choose 2 of them.
