Answer 7

Once you know he is an honor student, the denominator drops from 160 to just 40. And since 40 + 60 + 80 is 180 but there are only 160 students, 20 were counted twice so they must be both honor and athletes. So it's 20/40 or 1/2 that the student chosen is an athlete given that he is an honor student
