The Romba floor cleaning system is controlled by a computer that has three major modules. For the product to work all three modules, function correctly. Two of the modules have reliabilities of 0.97 ; the other module has a reliability of 0.99.a. What is the relability of the floor cleaning spotem?b. A backup computer identical to the one in place will be installed in premium models to improve overall reliablity. Aasuming the backsp will function automatically if the main one falls, what would be the resulting rellability?c. If the backup computer requires a switeh so activate it when the central computer fail, and the switch has the relability of 58, what is the overall relability of the nyatem?
