Assume that an engine service is made up of a large number, n, of individual tasks, and the time to complete each task follows an exponential distribution with mean M hours. Also assume that only one task can be done at a given time so that the overall time to completion is the sum of the individual task times. We tell the customer that they get a discount if the service takes us more than k×n×Mhours. What value for k should we use to ensure that there is a 90% chance that the customer pays full price?
