To calculate "choose" on a TI-83 calculator, you can use the combination function. Here's a step-by-step guide:

2. Make sure that the calculator is set to the "Normal" mode by scrolling down and selecting it if needed.
3. Press the [STAT] key and select the "PRB" menu by pressing the right arrow.
4. Scroll down to find and select the "nCr" option by pressing the down arrow.
5. Enter the value of "n," which represents the total number of items or possibilities. In your example, "n" is 5.
6. Press the [ALPHA] key followed by the [MATH] key to insert the "(" symbol (this is necessary since the syntax requires parentheses for the first argument).
7. Enter the value of "r," which represents the number of items you want to choose. In your example, "r" is 4.
8. Close the parentheses by pressing the [2nd] key followed by the [0] key. This will give you a closing parenthesis ")".
9. Press [ENTER] to calculate the result.
In your specific case, you would perform the steps above and get the result of 5 choose 4, which is 5.
Keep in mind that the combination function on the TI-83 calculator follows the convention of notation by using "nCr" instead of "C."
