= O PROBABILITY Intersection and conditional probability Suppose that a certain college class contains 62 students. Of these, 37 are seniors, 36 are mathematics majors, and 11 are neither. A student is selected at random from the class. (a) What is the probability that the student is both a senior and a mathematics major? (b) Given that the student selected is a mathematics major, what is the probability that he is also a senior? Write your responses as fractions. (If necessary, consult a list of formulas.) (b) X 1/5 S
