1. Entropy of functions of a random variable. Let X be a discrete random variable. Show that the entropy of a function of X is less than or equal to the entropy of X by justifying the following steps: H(X.g(X)) H(X) + H(g(X) | X) H(X,g(X)) H(g(x)) + H(X|g(X)) Thus H(g(X)) ≤ H(X). @H(X); > H(g(X)).

1. Entropy of functions of a random variable. Let X be a discrete random variable.
Show that the entropy of a function of X is less than or equal to the entropy of X by
justifying the following steps:
H(X. g(x))
H(X) + H(g(X) | X)
H(X);
H(X,g(X))
H(g(x)) + H(X | g(X))
Thus H(g(X)) ≤ H(X).
> H(g(X)).
