Math for "At Least One in N trials"
For the chance at an Artifact appearing after multiple trials is
(1 - ((V)^N)) x100 = C
V is chance of failure, N is number of trials - aka, how many times you "hit" or roll the event, and C is your answer in percentage format of getting 1 or more Artifacts
You can also write V as (1 - P), P being the probability of the event happening
(1 - ((1-P)^N)) x100 = C
(What the formula is doing is taking your chance of not getting an artifact x times in a row and subtracting it from 100%, this formula does NOT calculate your chance of getting 1 artifact, it calculates your chance of getting 1 OR MORE artifacts)
Example
(1 - ((1055/1075)^15)) x100 = C is the formula for 15 runs at the mystic gem room,
After 15 tries you chance of getting 1 or more Artifacts from the room would be 24.55%.
15 runs of skull key would be (1 - ((410/430)^15)) x100 = C
51.052% of getting one or more Artifacts
15 runs of Lich would be (1 - ((10591/10600)^15)) x100 = C
1.266% of getting one or more Artifacts
