1. The guidance system of a ship is controlled by a computerthat has three major modules. In order for the computer to functionproperly, all three modules must function. Two of the modules havereliabilities of .95, and the other has a reliability of .99.
a.What is the reliability of the computer? (Roundyour answer to 4 decimal places.)
Reliability _____
b. A backup computer identical to the one being used willbe installed to improve overall reliability. Assuming the newcomputer automatically functions if the main one fails, determinethe resulting reliability. (Round your intermediatecalculations and final answers to 4 decimal places.)
Reliability _____
c. If the backup computer must be activated by a switch inthe event that the first computer fails, and the switch has areliability of .98, what is the overall reliability of the system?(Both the switch and the backup computer must function in order forthe backup to take over.) (Round your intermediatecalculations and final answers to 4 decimal places.)
Reliability _____
