Best ResponseYou've already chosen the best response.0Erg. Ok look chika. I enumerated the possible outcomes for a test with 3 questions where each question had 2 answers.

anonymous

Best ResponseYou've already chosen the best response.0ok each of those lines is ONE possibility for the test to be solved

anonymous

Best ResponseYou've already chosen the best response.0Each line in my post was a way you could complete the whole test. Not one question.

Best ResponseYou've already chosen the best response.0so you wrote out the entire sample space

anonymous

Best ResponseYou've already chosen the best response.0Try something more simple. If you have two true or false questions how many ways can you answer them?

anonymous

Best ResponseYou've already chosen the best response.0I didn't want to try to write out the sample space for 8 questions because a) that would have given her the answer, and b) I didn't want to write 256 lines.

anonymous

Best ResponseYou've already chosen the best response.0the other way is to use multiplication rule for the first question there are 2 ways, second question there are 2 ways to answer, etc, so the total ways is 2 x 2 x 2 ...

Best ResponseYou've already chosen the best response.0kind of like a tree diagram

anonymous

Best ResponseYou've already chosen the best response.0so you can enumerate the entire space, as you did pol for your simpler example. or you can use product rule rather than enumerate 256 cases
