NUmber of ways to answer a question?

  1. Nov 29, 2005 #1
    A multiple choice question has 5 answers, anything from one to all the choices can be marked(more than one choice can be marked at a time). How many ways are there to answer the question? While waiting for on my chem question, I want to see how hard it would be to guess my way to the answer:rofl: I think I did this in precalc last year..something about series..I can't really remember.
