INTRO: Overview
Today we will continue the study of the random number
generator rand(), and its use for generating random integers in
some range, such as 1 to 6, or 1 to 52, that is useful to us.
We will look at how a histogram or bar graph can be used to make
sure that the random integers are well behaved.
We will consider some simple problems in which random integers
can be used to simulate the role of chance.
