P(≥1) = 1 − (1 − p)rolls  ·  rolls = budget($) × 8  ·  p = (Tier·Stage rate ÷ characters sharing that slot) × Finish rate

Finish rates are derived from GachaRoll.io's value multipliers — Color 1×, Holo 33× rarer, Dark Holo 970× rarer — normalized to 100% and applied flat across every tier and stage. Characters that share a Tier & Stage (e.g. all 25 Exalted-stage lynx-line variants) split that slot's rate evenly.
