Question: Suppose that an electronic system contains n similar components that function independently of each other and that are connected in series so that the system

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