Question: How many ways can 10 identical buttons, 10 identical bows, and 10 identical beads be distributed to 4 different people?
My thoughts: I decided to use the bars and stars method. With the knowledge that there are 4 unique groups of people, each person has the possibility of getting 1 of the 10 buttons, 1 of the 10 bows, and 10 of the 10 bows. I'm having trouble deciding whether the items are the elements or the actual people are the elements (the stars in this case). Your thoughts?
