(1) Refer to Problem B. It is H(Y ) > H(X). (1) True (2) False

(2) Refer to Problem B. It is H(Y |X) > H(X|Y ). (1) True (2) False

If you don't know how to get H(X) and H(Y) out of that table, you probably cannot answer the question. You use log to get H(X) and H(Y).

Problem B. Table 1 illustrates the joint probability distribution p(X, Y) of a communication channel. Output | Input + 2 2 P( Y ) y1 0.2 0.1 0.3 y2 0.3 0.4 0.7 P(X) 0.5 0.5 1.0 Table 1: Communication channel
