Answer #1

Let's use TI-84 Plus calculator

Suppose the probability  that the polygraph would have guessed correctly = 80% = 0.80

So here we need to find 0.80^10 or ( 0.80*0.80*0.80*0.80*0.80*0.80*0.80*0.80*0.80*0.80).

Click on 0.80 then ^ then 10 and then ENTER so we get the following output.

Similarly we can find any power of any value in the calculator.
