### Re: Crazy Fractions!!!

You changed the problem! It is different in the other thread!

This one is trivial. Of course there is no solutions.

They solve probability problems mostly. I show by example and leave the theorems to guys who hate numbers.

Nope, they are solved by computation. Do you have access to some computational engine?
