Recently I started playing a collectable card game after some friends got me into it. (Who themselves got back into it after some friends of theirs started playing. Witness the economic potential of viral card games!) As it turns out, I am a pretty poor card player I figured I would get into the business of collecting cards. Which is fun, you can do alone, and requires no skill.
I figured I would answer the question “If I started from scratch, how many booster packs would it take for me to collect the whole set”. Well, since booster packs give you cards randomly the best you can shoot for is a confidence interval.
