Hello Mark,

This is a fair question.  Suppose that I have three boxes with capacity
limits of 3, 2, and 1, and that there are three balls in total.  Two of the
possible distributions are the following:

2, 0, 1
2, 1, 0

Capacity limits of the individual boxes must be observed when distributing
the balls.  Even though the second and third boxes have different
capacities, we must treat the above two distributions of balls as
equivalent.

Combinatorics problems involving boxes with capacity limits arise in such
application domains as physics and reliability.
