Question

A short statistics quiz consists of two multiple choice questions. Each question had four possible answer choices (A, B, C, and D).

a. Make a list of the possible answer keys for the quiz or make a tree diagram for them.

b. How many possible answer keys are there?

c. If a student guesses at random for both questions, what is the probability they get both questions right?

d. What is the probability that C was not the correct answer to either question?

a quick quiz consists of true/false questions followed by a
multiple choice question with four possible answers (a,b,c,d). If

correct answer is to either question, but you mark an answer
anyway. What is the probability you have given the correct answer
to the multiple choice question? Enter your answer as a decimal
