Entropy of a discrete random variable with possible values {x1, x2, …, xn} and probability density function P(X) is :

The value of b gives the units of entropy. The unit for b=10 is :

(1) bits
(2) bann
(3) nats
(4) deca

(A) (1) and (3)
(B) (2) and (3)
(C) (1),(2)and(3)
(D) All are correct.


Answer: (D)
