When only the value-added time is considered, the time it takes to build a laser printer is thought to be uniformly distributed between 8 and 15 hours.
a. What are the chances that it will take more than 10 value-added hours to build a printer?
b. How likely is it that a printer will require less than 9 value-added hours?
c. Suppose a single customer orders two printers. Determine the probability that the first and second printer each will require less than 9 value-added hours to complete.
