Formula and assumptions

chance of at least one = 1 − (1 − p)ⁿ
expected openings to first = 1 ÷ p

The model assumes the same probability on every independent opening, with no pity, dynamic luck, changing pool or duplicate protection.

Expected openings versus a guarantee

Expected openings is a long-run average, not a deadline. For any chance below 100%, a finite opening count cannot guarantee a drop.

When this model does not apply

If the game changes odds over time, has pity, uses non-independent rolls or does not show a trustworthy probability, use the result only as a hypothetical scenario—not a prediction.

Game-specific presets

There are none yet. A preset will appear only after its exact probability and conditions have current, field-level evidence.
