A quiz consist of ten true-false questions how many possible answer keys are there?

This is simple, it's just an exponent.


Here's how you do it.


You have 2 possibilities for the first question


So we do 2 = 2^1





2 for the next


So we do 2 * 2 = 2^2





Then 2 possibilities for the next one


So we do 2 * 2 * 2 = 2^3





In the end we have 10 questions so it ends up being:


2*2*2*2*2*2*2*2*2*2 = 2^10 = 1024 possible answersA quiz consist of ten true-false questions how many possible answer keys are there?
20 POSSIBLE ANSWERS=2(FOR EACH QUESTION)*10(QUESTIONS)





*EXTREMELY SORRY FOR WRITING IN CAPS, I DIDN'T MEAN TO?A quiz consist of ten true-false questions how many possible answer keys are there?
Twenty





2(answer) x10(questions)=20 possible answer keys
20
400
20
20 i guess
