The mathematics department of a college has 15 male professors, 14 female professors, 8 male teaching assistants, and 14 female teaching assistants. If a person is selected at random from the group, find the probability that the selected person is a teaching assistant or a female.
The formula for probability is (number of succesful outcomes) over (number of possible outcomes). There are 22 teaching assistants and 14 non-teaching assistant females, so the probability is 36/51.
