The probability of transmission error in each of the servers and the proportion of messages that travel each route are shown in the following table. Assume that the servers are independent. Probability of Error Percentage of Messages Server 1 Server 2 Server 3 Server 4 Route 1 30 0.01 0.025 Route 2 70 0.02 0.017 (a) What is the probability that a message will arrive without error?
