You require 12 special event items to complete an objective

You have two opportunities:

  1. You can pay $2(gold/gems/doubloons/whatever) for a 33% chance at one
  2. You can pay $3 for a 50% chance at one.


The goal is to get all 12 for the lowest cost. The items are interchangable so you don't need to get a specific item, just a total of 12.

The naive impression is that both situations are equal, it should take an average of $72 in either case, but what's the real answer?
