We are given P(pass CPA) = 0.6. We are also given P(pass CPA AND get a job offer) = 0.4. They ask you about the conditional probability P(get a job offer | pass CPA). Use the general definition of the conditional probability P( A | B ) ] = P(A and B)/P(B). In your case, the event A = "get a job offer", the event B = "pass GPA"; the event (A and B) = (pass GPA AND get a job offer) Therefore, the conditional probability P(get a job offer | pass CPA) = P(A and B)/P(B) == .
