Answer #1

(a) the probability that the student is male = 169000/325000 =0.52

(b) the probability that the student dropped out = (54500+10400) / 325000 = 0.1997

(c) the probability that the student is male and dropped out = 10400/325000 = 0.032

(d) Given that the student is male, the probability that he dropped out = 10400/169000 = 0.6154

(e) Given that the student dropped out, the probability that the student is male = 10400/(10400+54500) = 0.1602
