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:

hypergeoametric distribution.  P(x) = (20C4 * 15C0) / 35C4

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]

Hypergeometric Distribution Problem 2:

You have 20 PS4 games and 15 Wii-U titles.  You grab 4 games at random and  Exactly 1 of them is a Wii-U game.  What is the probability of the event?

  1. 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.
