Here is how you can set up a random number generator.

- Set up the random number generator on a graphing calculator to generate a number from 1 through 100. (see screen shots below)
- If the numbers 1, 2, 3 or 4 are generated, this means a hurricane occurred.
- If any other numbers 5 – 100 are generated, no hurricane occurred.
