Tyson! I did my math wrong, I think?
I was using the jellybean equation instead of the card drawing equation. We aren't drawing like things from a selection of things, but individual things without replacement from a deck of individuals.
It's best to calculate the probability of Eldrad *not* getting fortune, then taking the inverse. = 1- ( (5x4x3x2)/(6x5x4x3)) == 67%

That's closer to what I thought it was. I was playing around with the math for awhile at work when I realized with the first equation as soon as you added a theoretical 5th roll it would go from 95% to 178%. Good to know the actual math now. Thanks.
