Ok, I'm hoping that one of the teachers here (or maybe a D&D expert) might be able to explain this to me.

In Diablo 3 when you pick up a Legendary quality item you then have to click on the item to roll to get it's stats (essentially a virtual dice roll). There is a 89% chance it will be a standard Legendary, a 10% chance it will be an Ancient Legendary and a 1% chance it will be a Primal Ancient Legendary which is a item with perfect max stats.

Why is it that after clicking on hundreds of Legendary items over the weekend not a single one of them rolled as Primal Ancient? I thought that if it has 1% chance of rolling as a Primal that clicking on 100 would guarantee 1 of them would be a Primal item.
