Suppose that a device stops working if one of its five components fails, and suppose that the lifetimes of the five components are exponentially distributed with means 10000,15000,20000,25000,and 50000 (in hours). Assuming that the component lifetimes are independent, what is the probability that the device keeps working for at least 10000 hours?
