Chapter 15.4, Problem 5P
A bit (meaning binary digit) is 0 or 1. An ordered array of eight bits (such as 01101001 ) is a byte. How many different bytes are there? If you select a byte at random, what is the probability that you select 11000010? What is the probability that you select a byte containing three 1 ’s and five 0 ’s?
