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.) Answers to different questions are independent. Jodi is a good student for whom p = 0.75. 1. Use the Normal approximation to find the probability that Jodi scores 67% or lower on a 100-question test.

A. 0.1150

B. 0.1251

C. 0.0322

D. 0.0104
