Suppose that an airline quotes a flight time of 140 minutes between two cities. Furthermore, suppose that historical flight records indicate that the actual flight time between the two cities, x, is uniformly distributed between 120 and 160 minutes. Letting the time unit be one minute. (a) Write the formula for the probability curve of x.
(b) Find P(140 < x < 150).
(c) Find the probability that a randomly selected flight between the two cities will be at least 6 minutes late.
