The following circuit operates if and only if there is a path of functional devices from left to right. The probability that each device functions is as shown. Assume that the prob- ability that a device is functional does not depend on whether or not other devices are functional. What is the probability that the circuit operates? Let A denote the upper devices function. Let B denote the lower devices function. (Show complete solution in your answer sheet) 0.70 0.80 0.95 0.95 0.95 0.90
