A subway train on the Red Line arrives every 11 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. Part (a) Define the random variable X. the number of commuter trains that arrive during rush hour the number of commuters waiting for the train . time, in minutes, that a commuter has to wait for the train time, in hours, that a commuter has to wait for the train Correct! The number of minutes a commuter has to wait for the train is the continuous random variable of interest. Part (b) Give the distribution of X.
