Suppose that an electronic system contains n similar components which function independently of each other and which are connected in series, so that the system fails as sn as one of the components fails. Suppose also that the length of life of each component, measured in hours, has an exponential distribution with mean. Determine the mean and the variance of the length of time until the system fails.
