I. Consider the following system: .90 190 Determine the probability that the system will operate under each of these conditions: 1. The system as shown. b. Each system component has a backup with a probability of 90 and a switch that is 100 percent reliable. c. Backups with 90 probability and a switch that is 99 percent reliable. 2. A product is composed of four parts. In order for the product to function properly in a given situa- tion, each of the parts must function. Two of the parts have a 96 probability of functioning, and two have a probability of 99. What is the overall probability that the product will function properly
