In a communication system the signal sent from point a to point b arrives by two paths in
parallel. For path 1, the signal passes through two repeaters ( in series ). Each repeater has
probability of failing ( becoming an open circuit ) of 0.1. For path 2, the signal passes through
one repeater with a probability of failing of 0.08. All repeaters fail independently of each
other. Find the probability that the signal will not arrive at point b.
