How to read “1 in N”

The Index displays labels such as 1 in 2 and 1 in 18. We transcribe those labels exactly. The captures do not expose the underlying random-number formula, pity rules, category weights or how Luck modifies each item, so this site does not convert them into guaranteed probabilities or expected cash cost.
