Extracted text: 4 A binary communication channel carries data as one of the two types of signals denoted by 0 and 1. Owing to noise a transmitted 0 is sometimes received as 1 and a transmitted 1 is sometimes received as a 0. For a given channel, assume a probability of 0.94 that a transmitted 0 is correctly received as a 0 and a probability of 0.91 that a transmitted 1 is received a a 1. Further assúme a probability of 0.45 of transmitting a 0. If a signal is sent, Determine: (a) Probability that a 1 is received. (b) Probability that a 0 was received.
