P4 (24 points). Twenty units of a newly designed components were designed to be deployed in a system that will operate for 500 hours for each component. During a burn in test in reliability One failed after 100 hours and one after 50hours. The rest of the components finished 500 hours of the test time. 4. Calculate Failure Rate \% (FR\%)?
