Here is a simple probability model for multiple-choice tests. 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 answers to different questions are independent. jodi is a good student for whom p = 0.85.(a) use the normal approximation to find the probability that jodi scores 78% or lower on a 100-question test.(b) if the test contains 250 questions, what is the probability that jodi will score 78% or lower?
