# Hypergeometric Distribution TI-84 | TI-83 Example

Joestat wants you to complete the following Hypergeometric Distribution examples using your TI-83 or TI-84 calculator.

### Hypergeometric Distribution Problem 1:

You have 20 PS4 games and 15 Wii-U titles.  You grab 4 games at random and  Exactly 4 of them are PS4 games.  What is the probability of the event?

First use the Hypergeometric Distribution Formula | Definition to set up the problem:

Second enter the hypergeometric distribution by entering it into your TI-84 or TI-83 calculator:
[(] | [2] | [0] | [MATH] | [<] | [3] | [4] | [*] | [1] | [5] | [MATH] | [<] | [3] | [0] | [)] | [%] | [(] | [3] | [5] | [MATH] | [<] | [3] | [4] | [)] | [ENTER]

Do you really have to put every damn figure and number in a [ ]. Who can read all that?

Dear GGG,

The reason we include all buttons within a [button] is to prevent the inputs from being on separate lines. Since tistats.com is 100% scalable and made for the various resolutions associated with mobile devices and printers, we came up with this idea as a solution new to their TI-83 or TI-84 calculator to learn. If you have any suggestions to alternatives to the problem please let us know.

The problem:
Those new to the calculator might have troubles with s
to>, so we use [sto>] to keep everything on the same line.

Thanks for your suggestion on how to improve the Hypergeometric Distribution TI-84 tutorial section.
