User blog comment:Fairingrey/A Complaint to Silicon Studio Regarding Mammon/@comment-25543593-20150122061225/@comment-1.64.154.250-20150124084958

Actually I have done a calculation before I started the Mammon hunting.

Assume the chance of pulling Mammon from greed is 1%, even if you have 500 greed card, Chance that you have only pulled 0 Mammon is 0.007

Chance that you have only pulled 1 Mammon is 0.04

In other words, you have 4% chance not getting Mammon even you have 500 greed card.
