    If a student is selected at random from those with a passing grade, what is the Probability that the student will receive a B or higher?

    A 6/25 B 6/22 C 9/25 D 9/22 E 8/25

    How many students passed? What's a passing grade? Are all grades equally distributed (ie: did the same number of people get an A as those who got a B)?
