A student is taking a multiple-choice quiz in which each question has four choices. Assume that the student has no knowledge of the correct answers to any of the questions any hence, all her answer are guesses. There are five multiple-choice questions on the exam. What is the probability that she will get: a.) no questions correct? b.) at least one question correct? c.) no more than two questions correct?
