In pulse- code modulation (PCM), a PCM word consists of a sequence of binary digits (bits) of 1s and 0s.

(a) Suppose the PCM word length is n bits long. How many distinct words are there?

(b) If each PCM word, three bits long, is equally likely to occur, what is the probability of a word with exactly two 1s to occur?
