Multiple-choice questions each have 6 possible answers, one of which is correct. Assume that you guess the answers to 3 such questions. Use the multiplication rule to find the probability that the first two guesses are wrong and the third is correct. That is, find P ( W W C ) , where C denotes a correct answer and W denotes a wrong answer. (round answer to 4 decimal places) P ( W W C ) = Incorrect What is...

Multiple-choice questions each have 5 possible answers, one of which is correct. Assume that you guess the answers to 4 such questions. Use the multiplication rule to find the probability that the first three guesses are wrong and the fourth is correct. That is, find P(WWWC) P(WWWC) , where C denotes a correct answer and W denotes a wrong answer. (round answer to 4 decimal places) P(WWWC)= P(WWWC)= What is the probability of getting exactly one correct answer when 4...

A student answers a multiple choice examination with questions that have four possible answers each. Suppose that the probability that the student knows the answer to a question is 0.80 and the probability that the student guesses is 0.20. If the student guesses, the probability of guessing the correct answer is 0.25. The questions are independent, that is, knowing the answer on one question is not influenced by the other question. (a) If there is one question on the exam...

A multiple choice test has 26 questions, and each has four possible answers, of which one is correct(i.e. the probability of guessing correctly is 0.25). If a student guesses on every question, a) find the probability of getting exactly 11 correct. b) Would it be unusual to guess correctly on exactly 11questions? Why?
