# Random Integer TI-84 | TI-83 Example

Use the TI-84 and TI-83 calculator to help simulate 15 random marriage dates given that there are 365 days in a year, each event is equally likely, and data is not unique.

Before you use the Random Integer function, make sure the following is true:

Each event is equally likely
Data is not unique

Random Integer (number) TI-84 and TI-83 example:
randInt( Lowest Value, Highest Value, Sample Size )

In our example:
Minimum possible outcome is 1
Maximum possible outcome is 365
Sample Size is 15

| [MATH] | [>] | [>] | [>] |  |  | [,] |  |  |  | [,] |   [)] | Next store it in a list to make things easier to read and record.
[STO>] | [2ND] |  | [ENTER] | Now you can easily view them in the L5 list.

Example Problem 2:  Now let’s simulate what would happen if I rolled a regular 6 sided dice 20 times.

Each event is equally likely
Data is not unique
Minimum possible outcome is 1
Maximum possible outcome is 6
Sample Size is 10

| [MATH] | [>] | [>] | [>] |  |  | [,] | [ 6] | [,] |   [)] | Next store it in a list to make things easier to read and record.
[STO>] | [2ND] |  | [ENTER] | Now you can easily view the results in L5 list.

Congratulations, you have successfully used the random integer function in your TI-84 or TI-83 calculator.
