Continuous Uniform Distribution

Question

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is less than 51.7 min.

P(X < 51.7) = ?

Answer 1

P(x < 51.7) = (51.7 - 50)/(52 - 50) = 1.7/2 = 0.85
