For each probability and percentile problem, draw the picture. A subway train on the Red Line arrives every 8 minutes during rush hour. We are interested in the length of time a commuter must wait for a train to arrive. The time follows a uniform distribution. A) Define the random variable X.
B) Graph the probability distribution.
C) Find the probability that the commuter waits between three and four minutes.
