Problem 10. (10 points) The amount of time it takes for a student to complete a statistics quiz is uniformly distributed (or, given by a random variable that is uniformly distributed) between 30 and 58 minutes. One student is selected at random. Find the probability of the following events. A. The student requires more than 52 minutes to complete the quiz. Probability= B. The student completes the quiz in a time between 36 and 41 minutes. Probability= C. The student completes the quiz in exactly 42.63 minutes. Probability= Note: You can earn partial credit on this problem.
