A test has three parts. Part A consists of three true-false questions, part B consists of three multiple-choice questions with five choices each, and part C requires you to match seven questions with seven different answers one-to-one. Assuming that you make random choices in filling out your answer sheet, what is the probability that you will earn 100% on the test? (Leave your answer as a formula.) O P(E) = 32 x 5³ x 7! 1 O P(E) = 23 x 75 x 3! 1 O P(E) = 23x 5³ x 7! 1 O P(E) = 72 x 53 x 3! O ME - 1 O P(E) = 2? x 35 x 3!
