How do we solve. Please be specific and note where each probability came from. For example if the probability of a,b,c,d,e working is 5/11 please be specific in explaining where the 11 came from and how we count that.

Problem 1 One way in which a computer network is classified is according to the arrangement of devices and communication lines. Such an arrangement is referred to as network topology. In a ring topology, the computers forming the network are arranged in series in a ring as shown below. Assuming that each computer has probability of failure p=0.05 in a given time interval, determine the probability that communication between computers A and E will break down during the specified interval. B D A E G F
