Suppose that a certain college class contains 49 students. Of these, 27 are sophomores, 26 are English majors, and 7 are neither. A student is selected at random from the class. (a) What is the probability that the student is both a sophomore and an English major? (b) Given that the student selected is a sophomore, what is the probability that she is also an English major?
