In a communication system the signal sent from point a to point b arrives by two paths in parallel. over each path the signal passes through two repeaters connected in series. each repeater in one path has a probability of failing (becoming an open circuit) of 0.002. for the other path, the probability of a repeater failing is 0.005. all repeaters fail independently of each other. find the probability that the signal will not arrive at point b.
