2. Suppose you take a multiple choice test with 10 questions, and each question has 5 answer choices (a. (10 points) b, c.d, e). What is the probability you get exactly 4 questions correct just by guessing? on)
4. Suppose that the next quiz contains 5 multiple choice questions with four choices for each questiorn (a, b, c, d). Unfortunately Esther forgot to study and chooses to randomly guess the answers What is the probability that a. The only question she gets right is the fifth question? b. She earns a satisfactory grade (considered, for this case, as an 80% or greater)? c. She gets no question right?

A short quiz has two true-false questions and one multiple-choice question with four possible answers. A student guesses at each question. Assuming the choices are all equally likely and the questions are independent of each other, the following is the probability distribution of the number of answers guessed correctly. What is the Probability of getting less than all three right? X 0 1 2 3 P(X) .1875 .4375 .3125 .0625 Group of answer choices a) 1.0000 b) .9375 c) .6250 d) .3125
Assume you are totally unprepared for a quiz but you decide to take it anyway and just guess at all of the answers. The quiz is 12 multiple choice questions each of which have 4 choices (that’s 1/4 chance of getting one right). What is the probability that you will pass the quiz if you need at least 8 questions correct in order to pass? Select one: a. 0.0115 b. 0.0008 c. 0.0004 d. 0.0028
4. A multiple-choice exam has 5 questions. Each question has 3 choices, one of which is the right answer. A student completes the exam by guessing. What is the probability that student gets 4 or more correct answers just by guessing?
