No actually you don't. You can't prove them wrong in one night, because that one night is far too small of a sample size to be considered proof.The idea that dice roll on a bell curb is far too well proven for it to be considered anything but a fact.The d10's you mention, are quite likely not true, as in they were manufactured with some sort of flaw that changes how they roll.and in one night I prove their statistics wrong..
As I said, been rolling dice for a while now.. haven't seen a statistic proven in that time..
Those 10s were just dice I pulled from a box in a store.. I am doubtful they were anymore flawed than the others in the box... but that possibility exists, I won't deny that.. flaws are always a possibility in the manufacturing process..
