Round your final answer to 4 decimal places.) b. Each system component has a backup with a probability of 72 and a switch that is 100 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places.) c. Each system component has a backup with a probability of 72 and a switch that is 97 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places.)
