Question 2: You have a multiple-choice test (4 options for each question) in your AP English class. You have studied and feel well prepared. You estimate that you have an 80% chance of knowing the answer and thus getting it correct. On questions you do not know, you plan to guess. Use this information to answer questions a- e below.

a) Make a tree diagram to model this situation.

b) What is the probability you answer a question correctly?

c) What is the probability that if I get a question right it is because I knew it?

d) What is the probability I get it correct given I guessed?

e) What is the probability I guessed given I got it correct?

Suppose that you are taking a multiple choice test (consisting of only 4-answer-choice questions) for which you have mastered 60% of the material. When you actually take the test, if you know the answer of a question, then you will answer it correctly for sure; if you do not know the answer, however, you can still guess the answer (meaning that you will have 25% chance of getting the correct answer). Finally, assume that your answer to each question is...

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...
