1. The problem statement, all variables and given/known data If a multiple-choice test consists of 5 questions each with 4 possible answers of which only 1 is correct, (a) In how many different ways can a student check off one answer to each question? (b) In how many different ways can a student check off one answer to each question and get all the answers wrong? I feel like if I could get a hint on (a) I could do (b) as well, but I am a little stuck trying to figure out which rule to apply. These are permutations correct? (the arrangement of answers.) Or should I just apply the "multiplication rule" somehow? Can I get just a hint here?
