5. A binary computer communication channel has the following error probabilities: P(R1 | S0) = 0.2, P(R0 | S1) = 0.06, where S0 = {'0' sent} S1 = {'1' sent} R0 = {'0' received} R1 = {'1' received} Suppose that 0 is sent with a probability of 0.8, find (a) The probability that '1' is received (b) The probability that '1' was sent given that 1 is received (c) The probability that '0' was sent given that '0' is received
