The guidance system of a ship is controlled by a computer thathas three major modules. In order for the computer to functionproperly, all three modules must function. Two of the modules havereliabilities of .86, and the other has a reliability of .98.
a. What is the reliability of the computer? (Round your answerto 4 decimal places.)
b. A backup computer identical to the one being used will beinstalled to improve overall reliability. Assuming the new computerautomatically functions if the main one fails, determine theresulting reliability. (Round your intermediate calculations andfinal answer to 4 decimal places.)
c. If the backup computer must be activated by a switch in theevent that the first computer fails, and the switch has areliability of .95, 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 intermediate calculations andfinal answer to 4 decimal places.)
