@venda saidC(n,k) is the number of ways of choosing "k" objects out of "n" objects.
O.k Joe,I am really fascinated by how these things are done but (only)if you have the time and patience could you one day explain in simple terms where some of the numbers come from. A pm will do if you don't want to clutter up the thread.
I get the 11!
I get the 8!
I get the 5!
Where I get lost is the (9,2) (7,2) and the 8! 7! 6!
its equal to
C(n,k) = n!/( k! (n-k)! )
Is that the issue we should first go deeper with?
