Suppose that each student has probability p of correctly answering a question chosen at random from a universe of possible questions. (A strong student has a higher p than a weak student.) The correctness of an answer to a question is independent of the correctness of answers to other questions.  Jennifer is a good student for whom p = 0.90.  You want to use the Normal approximation to find the probability that Jennifer scores 85% or lower on a 200-question test.
