How do you solve this?

28!/(28-28)!28! * 0.88^28 *0.12^28-28

I need help on how to solve this on a graphing calculator(TI-83 Plus) Can you help me?

Please show step by step instructions! Thank you!!!

To solve this expression on a TI-83 Plus graphing calculator, you can follow these step-by-step instructions:

1. Turn on your calculator and press the "MODE" button. Make sure that you are in one of the numerical calculation modes, such as "NORMAL" or "SCI."

2. Press the "MATH" button, then navigate to the "PRB" or "Probability" menu by using the arrow keys. Select the "nPr" function using the corresponding number or by pressing the corresponding number key.

3. Enter "28" as the first argument of the "nPr" function, followed by the subtraction sign ("-"), "28," and then "28" as the second argument. The expression should look like this: "nPr(28,28-28,28)."

4. Press the division sign ("/") on your calculator.

5. Next, press the "MATH" button again and navigate to the "PRB" or "Probability" menu. This time, select the "nCr" function using the corresponding number or by pressing the corresponding number key.

6. Enter "28" as the first argument of the "nCr" function, followed by "28" as the second argument. The expression should look like this: "nCr(28,28)."

7. Multiply this result by 0.88 raised to the power of 28. To do this, enter "0.88^28."

8. Multiply the previous result by 0.12 raised to the power of (28-28), which is 0. To do this, enter "0.12^0."

9. Multiply the results obtained in steps 7 and 8 together.

10. Finally, press the "ENTER" button to calculate the final result.

By following these steps, you should be able to solve the given expression on your TI-83 Plus graphing calculator.
