Sometimes multiple redundant backup components are used for complex "mission critical" systems such as military and civilian aircraft and the ICU wards in hospitals. The result is a very high system reliability for the product in question since failure would be catastrophic.
Determine the system reliability of a component that is 95% reliable with (not one, but) two backup components in parallel, each with a reliability of 95%. Hint: Resolve the "backup to the backup" first, then use this result as a backup for the original component.
