A switchable standby safety system is used to increase reliability in a protection

system. If the reliability of the main system is 0.90, that of the standby system is

0.91, that of the fault detector/switching system is 0.90, and the reliability of the

switch in normal operation is 0.96, calculate the reliability of the protection system.
