TI-84 Video: Generating Random Numbers 1. Be sure you "seed" your calculator. This will ensure that the same random numbers do not appear on everyone's calculator. Enter a random number in the calculator such as the student ID number or telephone number. Then press [STO->] [MATH] "PRB" "1:rand".
Note: This step only needs to be completed once unless you reset the calculator! Â And you will not get the same numbers!

2. Specify the minimum and maximum integers possible, and how many random integers to generate. For example, [MATH] "PRB" "5:randInt(1,10,5)" [ENTER] generates 5 numbers between 1 and 10.
Note: Hit [Enter] to get 5 more random numbers between 1 and 10. Of course, you will not likely get the same random numbers.

3. To simulate flipping a coin, let '0' be heads and '1' be tails. For example, [MATH] "PRB" "5:randInt(0,1,6)" [ENTER] generates 6 numbers between 0 and 1. All of the '0's are Heads. All of the '1's are Tails!
The image below shows 3 heads and 3 tails. Then it shows 4 heads and 2 tails.

![To simulate rolling dice, go to [MATH] "PRB" "5:randInt(1,6,2)" [ENTER] generates 2 numbers between 1 and 6.](https://media.screensteps.com/image_assets/assets/001/997/657/original/862735B3-041F-4B03-AF81-AA4BB3E8E008.png)
![You could also generate a lot of numbers and store them in a list. For example, [MATH] "PRB" "5:randInt(1,10,100" [ENTER] generates 100 numbers between 1 and 10. Then [STO->] [2nd] 'L1' will place the numbers in List 1.](https://media.screensteps.com/image_assets/assets/001/997/658/original/5364820E-8AFB-4003-8D44-BF11C0F63589.png)
