Ed and Taylor work together on a group quiz that has 20 multiple-choice questions, each with 5 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 10 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 =
