Q2: A simple binary communication channel carries messages by using only two signals, say O and 1, we assume that, for a given binary channel, 30% of the time a 1 is transmitted; the probability that a transmitted 0 is correctly received is 0.8, and the probability that a transmitted 1 is correctly received is 0.85. Determine: 1.The probability of a 1 being received 2.Given a 1 is received, the probability that 1 was transmitted
