Ed and Taylor work together on a group quiz that has 15 multiple-choice questions, each with 4 choices for the possible answer. Unfortunately, neither had time to study, so they decide to randomly guess at all answers. Ed guesses answers for the first 5 questions, and Taylor guesses for the other 10 questions. (a) For any single question on the quiz, what is p = chance of a correct guess? p = (b) Let X = number of correct guesses that Ed makes. What are the values of n and p for the binomial distribution that describes X? n = p = (c) Let Y = number of correct guesses that Taylor makes. What are the values of n and p for the binomial distribution that describes Y? n = p = (d) Consider X + Y = total correct guesses that Ed and Taylor make. What are the values of n and p for the binomial distribution that describes X + Y? n = p =
