An exam consists of 64 independent multiple-choice questions. For each question, there are five choices, with only one being correct. Suppose a student randomly guesses the correct answer to each question. (a) What are the mean and standard deviation of the number of successful guesses? (b) Use the normal approximation to find the probability that the student will correctly guess at most 10 correct answers.

There are five multiple choice questions on an exam, each having responses a, b, c, and d. Each question is worth 5 points, and only one option per question is correct. Suppose the student guesses the answer to cach question, and these guesses, from question to question, are independent. If the student needs at least 20 points to pass the test, the probability that the student passes is closest to: O 0.0146 O 0.0156 0.001
