Find the MTTF and the reliability at the end of the first year for each of the following configurations. (a) Two identical subassemblies configured as a standby system with annual com- ponent failure rates of .08 and .12 and standby annual component failure rates of .01 and .04 (components A and B respectively). (b) Two identical subassemblies operating as a load-sharing system with annual component failure rates of .08 and .12 and shared-load annual component fail- ure rates of .05 and .09 (components A and B respectively)
