Two Random Exercises August 17, 2012 We have two exercises
related to random numbers today. I’m not sure of the source, but
they look to me like homework exercises. First, given a function
rand3 that returns a number from 1 to 3 inclusive chosen at
random, write a function that returns a number from 1 to 9,
inclusive. Second, given a function rand5 that returns a number
from 1 to 5 inclusive chosen at random, write a function that
returns a number from 1 to 7, inclusive. In both cases all
possible output numbers should be generated with equal
frequency. You should demonstrate that your functions behave
properly. Your task is to write the rand9 and rand7 functions
and demonstrate that they work properly. When you are finished,
you are welcome to read or run a suggested solution, or to post
your own solution or discuss the exercise in the comments below.
