Hi, I'm new here are need help for one of my math homework problems on permutations/combinations. I've been trying to solve this for a while but I still have no idea how to solve this problem. The rules for this problem are that 1) there is no rule stating that you must choose both a vegetable and sauce nor is there rule stating that you can only choose once and 2) the order doesn't matter (e.g. lettuce and ketchup is the same thing as ketchup and lettuce). I would really appreciate some help, thank you.
