A personal computer system is composed of the processing unit, graphics board, and keyboard with reliabilities of 0.976, 0.785, and 0.893, respectively. this is a series system and even if one component fails, the computer will not function correctly. the reliability of this system is
we can calculate the reliability of the system by multiplying reliabilities of the processing unit, graphics board, and keyboard reliability of processing unit = 0.976 reliability of graphics board = 0.785 reliability of keyboard = 0.893
