A three-circle Venn diagram summarizes 75 students. The regions are: only Review Path X = 16, only Review Path Y = 14, only Review Path Z = 10, Review Path X and Review Path Y only = 5, Review Path X and Review Path Z only = 9, Review Path Y and Review Path Z only = 6, all three = 3, and none = 12. Among those in Review Path X, what is the probability that a person is also in Review Path Z?
