Thank you, I will take a look.
Trying to find what could possibly go wrong I was wondering also if the assumption of independence of events is still valid if two dice collide. So I would toss the dice one after the other just in case, as the math behind assume rolls are independent events.
If you look at lottery events they probably use a machine to roll dice to guarantee independence of events. I don't want to be too paranoid there too and discourage you though.
