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] | [>] | [>] | [>] | [5] | [1] | [,] | [3] | [6] | [5] | [,] | [1] [5] [)] |

Next store it in a list to make things easier to read and record.
[STO>] | [2ND] | [5] | [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] | [>] | [>] | [>] | [5] | [1] | [,] | [ 6] | [,] | [2] [5] [)] |

Next store it in a list to make things easier to read and record.
[STO>] | [2ND] | [5] | [ENTER] |
Screenshot storing L5 in the TI-84

Now you can easily view the results in L5 list.

| [STAT] | [1] |

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