An exam has three questions. You estimate your probability of getting the first question right is 0.7, your probability of getting the second question right is 0.6, and your probability of getting the third question right is 0.5. Let Y be a random variable that is the number of questions you get right on the exam. What is the distribution ofY?

9. There are 50 true-or-false questions on an exam. For each question there is only one correct answer. If you need to get at least 65% of the questions correct to pass the test, what is the probability of passing this test by making random guesses? 10. Referring to the previous problem, find the mean (expected value) and variance for the number of questions you answer correctly by making random guess.

1.) You are taking a six-question quiz, where each question has three possible responses. If you guess randomly on each question, what is the probability that you get at least five questions correct? 2.)

On a certain statistics exam, there are 9 multiple choice questions. Each question has 5 possible answers to choose from (and only 1 correct answer). Suppose you didn’t study at all and are planning on guessing the correct answer for each question. Therefore, the probability of guessing a question correctly is ___________ . (Round to two decimals)   Let X = number of questions the student guesses correctly (Round all answers to four decimals) a)      What’s the probability you guess at...

Suppose you are taking an exam that only includes 80 multiple choice questions. Each question has five 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 less than five questions are needed to mark the three correct answers is
