A flight arrives at a random time, uniformly distributed between 6:00 pm and 6:30 pm. Find the probability that the flight arrives
(a) before 6:10
(b) between 6:15 and 6:25
(c) after 6:20
(d) before 6:20
(e) between 6:05 and 6:25
(f) after 6:10

Let X be the random variable "number of minutes after 6:00 at which flight arrives". Then the pdf of X is f(x) = 1/30 for and zero otherwise. Use this pdf to calculate the answers.
