dealt 3 cards from 52. what is the probability all 3 cards are picture?

We have 12 "face" (picture) cards in a deck

So the total number of sets possible in dealing three cards out of 52 is just C(52, 3)  = 22100

And we are interested in choosing the sets containing any 3 of the 12 face cards = C(12, 3)  = 220

So....the probability is just    220 / 22100  = about .99%
