WebLast Problem: There are 12 face cards in a standard deck (4 jacks, 4 queens, and 4 kings), and 40 non-face cards. Since we're drawing without replacement, we'll consider each card draw as a Bernoulli trial with a probability of success of 12/52 (or 3/13) for drawing a face card. Let X be the number of face cards drawn in three card draws.
