2) On a TrueFalse quiz there are two options – true or false. That means the probability of getting all questions right by randomly guessing is the same as the probability of getting all questions wrong by randomly guessing. Now think about a multiple choice question with three options – A, B or C. Do you think the probability of getting all questions right by randomly guessing is the same as the probability of getting all questions wrong by randomly guessing? Explain.
