Solution 13322: Using the RandInt() Function on the TI-84 Plus and TI-83 Plus.

How do you use the randInt() function on the TI-84 Plus and TI-83 Plus?

Please Note: It is necessary to set the seed value, if you have not previously, by following the steps in KB#34503.

The randInt() function generates and displays a random integer within a range specified by lower and upper integer bounds for a specified number of trials. The syntax for the randInt() function is listed below.

randInt( lower,upper[,number of trials]

Example: Find three random integers between 1 and 6:

1) Press [MATH]
2) Press the [Right Arrow] three times to go to the PRB menu
3) Press [5] to select the command randInt
4) Press [1] [,] [6] [,] [3] [)]
5) Press [ENTER]

Please Note: The numbers you receive may be different then the numbers displayed above since the numbers are randomly generated.
