each relic has a 10% chance of getting what you want, so 90% chance to not get the drop you want. If we're calculating the chance of getting at least one rare, we need to multiply that 90% for each successive player. 90% * 90% * 90% * 90% comes out to a bit over 65% chance of getting nothing across four rolls. Turn it over, and we get 34% chance of happiness.
