-
- The reason I posted it was because I saw a vey
- interesting solution to this problem.
-
- Add two identical `oranges' to this collection
- of apples. The total number of ways of arranging
- this new collection (i.e., permutations) is
-
- FACTORIAL(25+2) / ( FACTORAL(25)*FACTORIAL(2) )
-
- Now observe that each of the permutation is a way of
- dividing the apples among three people!!
-
- Of course this can be generalized into the problem of
- dividing `n' similar objects among `m' people.
