How many ways are there of selecting one of each face card from the pile?
There are three types of face card, K, Q, J.
There are four of each type.
#of ways to choose a "K" is 4C1 = 4
#of ways to choose a "Q" is 4C1 = 4
#of ways to choose a "J" is 4C1 = 4
# of ways to choose one of each is 4*4*4= 64
