How many ways can you distribute 4 identical balls among 4 identical boxes?
I'm stuck on this one
4-0-0-0
3-1-0-0
2-2-0-0
2-1-1-0
1-1-1-1
We don't need things like 0-0-3-1, 0-0-2-2 etc. because they're identical and would be the same thing.
So there are only 5 cases.
Hope that helps and please correct me if I'm wrong
We have (4+1)!/4!=5 so we have 5 ways to distribute 4 identical balls among 4 identical boxes
