In an experiment, a person guesses which one of three different cards a researcher has randomly picked (and hidden from the person who guesses). This is repeated four times, replacing the cards each time. Let X = the number of correct guesses in the four tries. The probability distribution for X, assuming the person is just guessing, is partially provided below. X 0 1 2 3 4 P(X) 0.20 0.39 0.30 0.10 a. What is the missing probability? [AnswerA] b. What is the probability that the person would get at least 3 correct guesses? [AnswerB] c. What is the probability that the number of correct guesses is at most 2? [AnswerC]
