I'm working on probabilities in my math class. It's a two part question:
1. Suppose you are dealt a hand of 3 cards out of a stack of 12 face cards (king, queen, and jack). How many possible combinations of the 12 face cards taken 3 at a time can there be?
The answer I got was 220 and I'm pretty positive I'm right.
2. How many different combinations can there be, such that, you will be dealt exactly two kings?
I'm not sure how to get the second part of the question. What would be the proper formula?

1. ok !!
2. [4 kings, get 2] * [8 others, get 1] = 6*8 = 48 <---------
