A commuter drives from his home to his office and from his office to his home every weekday. The ten, independent trips each take a normally distributed amount of time with an expected value of 40 minutes and a standard deviation of 10 minutes. (a) Determine the probability distribution of the commuter's total driving time during one day. (b) Determine the probability distribution of the commuter's total driving time during one week. (c) Determine the probability distribution of the commuter's average driving time per trip during one week.
