Fifty percent of students enrolled in calculus class have previously taken pre-calculus. Thirty percent of these students received an A for the calculus class, whereas twenty percent of the other students received an A for calculus. Find the probability that a student selected at random previously took pre-calculus and did not receive an A in the calculus class.

100 students
50 had pre calc - 15 got A, 35 not A

50 no pre cacl - 10 got A, 40 not A

sure looks like 35 of the hundred :)
