How the numbers work
Chance of an item = slot chance Γ (item weight Γ· total weight of the slot).
Chance of at least 1 = 1 β product over slots of (1 β that item's chance in the slot). Slots are rolled independently.
Expected amount = sum of chance Γ average quantity ((min + max) Γ· 2). Treat it as an average over many openings.
Weights and chances are the values in the game's loot tables. Rows with zero weight never drop and are left out; identical rows in one slot are merged.
