Having played a PnP game, I happen to know that a D20 has 20 sides given a 5% chance on average per outcome.
I currently am in possession of a magical D20 which i may roll to get cards which i may trade for stuff.
It is apparent however that a magical D20 does not give a 5% chance or either a card IX or card X which any normal D20 would give.
Not even a 5% chance that is then split in some way by another roll.
So i am curious has anyone worked out the actual probabilities here? we could with a large enough sample (if people could post what htye have received).
I have, for example, not used any cards and have accumulated the following:
I = 7
II = 3
III = 7
IV = 6
V = 8
VI = 5
VII = 9
VIII = 4
IX = 1
X = 0
So mostly these look about the same... That is 50 cards and i they were even amoung the 10 it would be 5 of each. a little higher or lower is not too weird but card X and IXis an exception.
the probability of not getting a card in 50 rolls if it was actually a 5% chance is buy the way 0.95^50 = approx 7%
but i have talked to other people and so i know it is not bad luck, it is a bad die. Clearly fixed.
Anybody else have some clean data for analysis?
