3. The Romba floor cleaning system is controlled by a computer that has three major modules. In order for the product to work all three modules function properly. Two of the modules have reliabilities of .97; the other module has a reliability of .99. a. What is the reliability of the floor cleaning system? b. A backup computer identical to the one in place will be installed in premium models to improve overall reliability. Assuming the backup will function automatically if the main one fails, what would be the resulting reliability? c. If the backup computer requires a switch to activate it when the main computer fails, and the switch has reliability of .98, what is the overall reliability of the system? 4. A service has four major components required for completion and delivery to the consumer. The component reliabilities are, .90, .94, .95, and .98. All four components must be preformed for the service to take place. a. What is the reliability of the current service offering? b. The boss wants to improve reliability by providing a backup. Because he/she is cheap they have informed you that they will only backup one of the four components with a identical component. (The backup will have the same reliability as the component it is replacing). Which component should get the backup in order to achieve the highest reliability? c. If one backup that has a reliability of .93 can be added to any of the main components, which one should get it to achieve the highest overall reliability
