Multiple choice questions on a test each have 4 possible answers, one of which is correct. Assume that you guess the answers to 3 such questions. Use the multiplication rule to find the probability that the first two guesses are wrong and the third guess is correct. That is, find P(WWC) where W denotes a wrong answer and C denotes a correct answer. Round your answer to 4 decimal places. [WWC] On your scratch paper, make a complete list of the different possible arrangements of 2 wrong a 1 correct answer. What is the probability of each combination? Round to 4 decimal places. [comb] What is the probability of getting exactly 1 correct answer when 3 guesses are made? Round to 4 decimal places. [one]
