Starting with a component that has a failure rate of l, compare two different ways of improving reliability: (a) by placing a second component in parallel and (b) by placing a second component in standby. What is the reduced equivalent failure rate of (a)? Of (b)? Comment on what you think the comparative cost would be to achieve the same reductions if (b) is used.
