54. How many ways are there to distribute five indistinguishable objects into three indistinguishable boxes?
A: Similarly to everyone else, I just made a table for the possible situations.
| 5 | 0 | 0 | | | | | | 4 | 1 | 0 | | | | | | 3 | 2 | 0 | | | | | | 2 | 2 | 1 | | | | | | 1 | 3 | 1 |
These are all 5 possible cases. There would be more cases for each entry, such as on the top line (5,0,0) (0,5,0) (0,0,5). But because these are indistinguishable boxes, you only count one of the three cases per possibility.
The answer is 5.
