Question

What is A&B&C? Please 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 33 and 62 minutes. One student is selected at random. Find the probability of the following events. The student requires more than 56 minutes to complete the quiz. Probability = ___________ The student completes the quiz m a time between 38 and 43 minutes Probability = ___________ The student completes the quiz in exactly 40.77 minutes Probability = ___________

Explanation / Answer

X ~ U(33, 62)

A) P(X > 56) = (62-56)/(62-33)

= 6/29

= 0.21

B) P(38<X<43) = (43-38)/(62-33)

= 0.17

C) P(X = 40.77) = 0
