This year, there is a 4% chance of a hurricane passing by Ocean City, Maryland.

Check Your Understanding

Here is how we will set up the number generator for this situation.

  • 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.

Here are screen shots on how to set up the graphing calculator as a random number generator.

This graphing calculator screen shot shows the Probability menu under the Math key function. Selection 5, rand int, is selected. Rand int is the selection for random integer

Press MATH, right arrow to PRB, and select 5:randInt(

This means a random integer generator.

This graphing calculator screen shot is of the home screen with the command rand int one comma one hundred. This command means for the calculator to generate random integers from one to one hundred.

In the randInt( feature, the first number is the lowest number to generate, and the second number is the highest number to generate.

randInt(lowest, highest)

 

When you press the ENTER button, a number is randomly generated.

This graphing calculator screen shot is of the home screen where the command rand int one comma one hundred has been activated. The random number thirty seven has been generated by the calculator.

A 37 was generated on this calculator. Based on the assignment of numbers, this 37 means that there was no hurricane.

Press ENTER again. Another number should be generated.

This graphing calculator screen shot is of the home screen where the command rand int one comma one hundred has been activated again. The random number one has been generated by the calculator.

This time a "1" is generated. This means a hurricane did occur!
