How to Use Random Generator in TI-84

In this tutorial, we will show you how to use the random generator feature on the TI-84 graphing calculator.

Step 1: Accessing the Random Generator

  1. Turn on your TI-84 calculator.
  2. Press the 2nd button, located in the top-left corner of the calculator.
  3. Press the 0 button to access the catalog.
  4. Scroll down through the available options using the arrow keys until you find rand(.
  5. Press the Enter button to select the rand( function.

Step 2: Generating Random Numbers

  1. After selecting the rand( function, the calculator will display rand().
  2. To generate a random number between 0 and 1, simply press the Enter button again. The calculator will display a random decimal number.
  3. If you want to generate a random whole number within a range, you can use the following formula: randInt(A, B). Replace A and B with the desired range limits.
  4. For example, to generate a random whole number between 1 and 10, input randInt(1, 10) and press Enter.

Step 3: Utilizing Random Numbers in Calculations

  1. Once you have generated a random number, you can use it in calculations by storing it in a variable. To do this:
  2. Press the STO> button, located below the ALPHA button.
  3. Enter the name of the variable you wish to assign the random number to (e.g., A), and press the Enter button.
  4. The random number will now be stored in the variable for future use.
  5. You can then use this variable in any calculations or equations you want to perform.

Conclusion

In this tutorial, we learned how to access and use the random generator function on the TI-84 graphing calculator. We explored generating random decimals and whole numbers within a specified range and storing them in variables for further calculations.
