Question 1166796: Suppose that at any sitting of BUSI319, 35% of the students are first year; 30% are second year; 25% are final year and 10% are qualifying to enter various programs (assume mutually exclusive). From records of the Statistics department, it was found that 20% of the first year students get A; 30% of the second year students get A; 35% of the final year students get A; 25% of the qualifying students get A. What is the probability a randomly chosen student will get an A? Given that a student got an A, what is the probability the student was first year? Second year? Third year? Qualifying?
