Problems 31-36
These are conditional probabilities, so first find the number of possibilities
by looking at the altered sample space. For Problem 31, P(face card) has s = 12
since there are four jacks, four queens, and four kings. Also, n = 52 since
there are 52 cards. However, for P(face card | jack) alters the sample space to
include only the four jacks. For this conditional probability, s = 4 and
n = 4. See Example 10.
