4-A ternary communication system is represented by conditional probabilities P(2r/1s) -0.1, P(2r/2s)=0.9, P(1r/0s)-0.1, P(1r/1s)-0.9, P(Or/0s)=0.9, P(Or/2s) 0.1. Suppose that input symbols 0,1, and 2 occurs with equal probability. Find the probability of the output symbols. Then, suppose that a 1 is observed at the output what is the probability that the input was 0?
