SUMMARY

The discussion centers on calculating the number of ways to answer a multiple-choice question with 5 possible answers, where any combination of answers can be selected. The solution involves recognizing that each answer can either be chosen or not, leading to a total of 2 options per answer. Therefore, the total number of ways to answer the question is calculated as 2^5, resulting in 32 distinct combinations.

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:smile: I think I did this in precalc last year..something about series..I can't really remember.
