Re: permutation

Hi;

Before getting to work on this one would you care to please comment on the last couple of yours I worked on.

Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Re: permutation

I never get any answers back from you.

Think of the problem as 5 different awards and 5 no awards given to 10 people. Now it is just a "Mississippi" problem.
