Suppose that a finite class contains 40% freshmen,10% sophomores, 10% juniors, and the rest seniors. Suppose that 10% freshmen, 30% sophomores, 60% juniors, and 70% of seniors pass the class. Answer the following questions: 1.Given that the student is a sophomore, what is the probability that she fails the class? 2.What is the probability that a randomly selected student passes the class? 3.What is the probability that a randomly selected student is a senior that passes the class?
