it would be a 2/30 chance

Ezequiel Gardner · Answer 2

30 students in total

20 male

10 female

22 have an A

8 don't have an A

Probability of randomly choosing a male = 20/30=2/3

Probability of randomly choosing subside who does not have an A = 8/30 = 4/15

Probability of choosing a male who does not have an A = (2/3) * (4/15) = 8/45
