I hope I've started this thread in the right section of the forum. I have the following problem. I have created a quiz that consists of 31 questions. Most of the questions have 6 possible answers to choose from, but some have fewer than 6. I'd like to know how many different ways a person could theoretically answer this quiz - that is, how many different combinations of answers are there? Only one answer can be chosen for each of the 31 questions. I'm guessing that the questions that have fewer than 6 available answers to choose from will make a difference to the answer, so here is the full breakdown of how many options are available for the person completing the quiz to choose from for each question.
The reason I'd like this answer is so I can tell the person who is completing the quiz (which is to be a featured in a book) exactly how unique their collective answers are. Thanks to anyone who can help!
