1. The problem statement, all variables and given/known data Find the number of ways to distribute 55 identical coins among three people, so that everyone gets an odd number of coins. 2. Relevant equations Stars and Bars Formula 3. The attempt at a solution (n+r-1,n-1) Ways to place r indistinguishable objects into n distinguishable boxes. C(57,2)=1596 total ways Thats about it. If it was even I could use same formula I think but with groups of objects instead. Since its odd I'm unsure. My weak guess was I took 55/3 and used the same formula and got roughly 196 total ways I'm sure that is wrong though. Thanks for any help.
