Suppose you are taking an exam that only includes multiple choice questions. Each question has four possible choices and only one of them is correct answer per question. Questions are not related to the material you know, so you guess the answer randomly in the order of questions written and independently. The probability that you will answer at most one correct answer among five questions is ?

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.

Richard has been given a 12-question multiple-choice quiz in his
history class. Each question has four answers, of which only one is
correct. Since Richard has not attended the class recently, he
doesn’t know any of the answers. The success occurs if Richard
answers a question correctly and the failure occurs if Richard is
unable to answer a question correctly. Assuming that Richard
guesses on all 12 questions, find the probability that he will
answer no more than 3 questions...
