Suppose that a certain college dass contains 62 students. Of these, 30 are freshmen, 38 are chernistry majors, and 5 are neither. A student is selected at random from the dass. (a) What is the probability that the student is both a freshman and a chemistry major? (b) Given that the student selected is a freshman, what is the probability that he is also a chemistry major? Write your responses as fractions. (If necessary, consult a list of formulas.) (a)I (b)D Suppose that a certain college dass contains 62 students.
