I am going to get a little sleep. See you later.

There are a lot of possibilities here.
Anyway, we can easily extend the recursion if not the formula for any number of variables and experiment with the terms.

Oh yes and quite useless unless you have exactly 4 colors.

Looks like the worst is over. Now about that formula...
If we hold k = 4 and vary n then we come up with this:
for n = 2, 3, 4, ...

I will play with it a little in a bit. Right now there is a little bit of an administrative matter to watch for.
I think we can't write a formula like that when the number of marbles are different for different colors, since it involves permutation?
Anyway, I'll stop here, spent almost a day on this one!

No problem! Thank you for the formula.

There is a typo in the formula. In post #26 there is (k-i), in post #34, (k-j).
It causes problem like flooring if it's not written..
In python, we need to convert it to float.
