if there is 22 true/false questions, how many possible combinations of answers would there be ?

Answer 1

Each question has 2 possible answers so you need to multiply 2 by itself 22 times. 2^22 is your answer.

Hope this helps. Good Luck. :)

Answer 2

Each question is independently true or false, so there are 2^22 ways, about 4 million. (4,194,304). The possibilities match up 1-for-1 with the integers 0 to 2^22 - 1, as you can tell by looking at the binary expansion for those numbers, with 1 meaning true and 0 meaning false.

Answer 3

22 questions
1 possible answer for each
2 possible choices
22X2=44

Answer 4

Combinations: 44
Permutations (when order matters): 4194304
