11 people want to participate in a competition. The number of people in a group can only be 2 or 3 In how many groupings can the friends enter into the quiz? I found out that there care only two types of groupings that are possible: 1 group of 3 and 4 groups of 2 3 groups of 3 and 1 group of 2 Now the problem is who's in which group. I first tried to put 11 letters (ak) and started counting, but it soon became confusing and hard to keep up with. Is there another way to find all the possibilities?
