The network operator wants to recongure the network so as to maximize the probability of a message actually getting delivered from station A to station (I. The same three links L1, L2 and L3 with reliabilities of ?U%, 80% and 60% respectively need to be used in the reconfigured network and there should be exactly one link from station A to station E and exactly two links between station E and station (I. But we are free to decide which of the three links should be from station A to station E. Find the best network conguration that will maximize the probability of a message from station A to station C being delivered. As before assume that a message dispatcher is well aware of the failure status of each link before dis patching the message. An additional direct link L4 is now added between stations A and (I. But L4 has only 49% reliability and the probabilities of failure of each of the four links L1, L2, L3 and L4 are independent of each other. Assuming again that a message dispatcher is well aware of the status of each link, what is the probability that a message actually gets delivered from station A to station E
