Suppose that a certain college class contains 45 students. Of these, 23 are sophomores, 23 are physics majors, and 8 are neither. A student is selected at random from the class. (a) What is the probability that the student is both a sophomore and a physics major?
(b) Given that the student selected is a sophomore, what is the probability that he is also a physics major?
