If there are 40 students, 22 are men, 10 are earning an A, and 7 are men that are earning an A, that means that there are 18 females, 10 total students making an A, 15 men that are not earning an A, and 3 females that are earning an A. (This is all given information) The question asks, if you select an "A" student, what is the chance that this student is a man? Remember, out of 10 A students, 3 are women and 7 are men. So the answer would be 7/10.
