Probability of the system-in continual operations

Reference no: EM1386589

A certain component is critical to the operation of an electrical system and must be replaced immediately upon failure. If the mean lifetime of this type of component is 100 hours and its standard deviation is 19 hours, how many of these component must be in stock so that the probability of the system is in continual operations for the next 2,000 hours is at least 0.95?
