Suppose you have a system with two components that must operate in series, and both must be operating for the system to be operational. The failure rates for these two components are: 1 = 0.5 failure per day 2 = 0.15 failures per day Also suppose the Mean Time to Repair (MTTR) of the components are: MTTR1 = 2 hours MTTR2 = 9 hours What is the repair rate () for the system? Group of answer choices 0.28 repairs/hour 1.2 repairs/hour 0.45 repairs/hour 0.22 repairs/hour
