Delta Airlines quotes a flight time of 2 hours, 4 minutes for a particular flight. Suppose we believe that actual flight times are uniformly distributed between 2 hours and 2 hours, 32 minutes.

A) What is the probability that the flight will be no more than 4 minutes late?

B) What is the probability that the flight will be more than 8 minutes late?

C )What is the expected flight time, in minutes?

Given an airline that flies between two cities with a quoted flight time of 2 hours and 10 minutes (130 minutes). Historical records indicate that the flight time between the two cities varies from 2 hours (120 minutes) to 2 hours and 20 minutes (140 minutes). The flight times are uniformly distributed. What is the probability that the flight will be between 125 minutes and 135 minutes?
