Suppose you are randomly guessing on a multiple-choice question with 1 question, 5 choices (A, B, C, D, E). If you guess correctly, you gain one point. If you guess incorrectly, you lose 1/2 point. If you leave the question blank, you get 0 points. Part 1) Create a probability distribution for the number of points you gain or lose. Part 2) Calculate and Interpret the Expected Value number of points. Part 3) Based on your answer to part 2, would it be better to guess or to leave it blank? Why?
