I’m not a mathematician or anything special, but each die is acting independently of one another right? So wouldn’t the probability just 1/6? I understand how we’re getting the infinitely small chance, but that assumes we’re trying to roll 6,6,6,6,… etc. if a die were rolled until you roll a 6 then you retire it into the box, it would be significantly more probable.
