Electric E supplies power to a large plant through a number of electric generators. The company is concerned with generator failures as a breakdown costs $75 per generator per hour. Maintenance technicians work rotating 8-hour shifts (the company therefore runs 24 hours a day). Management wants to determine the machine breakdown cost, for a simulation of 10 breakdowns. 5.1 Complete the tables below.
