Formula

P(bust) = |{v ∈ [min,max] : hand+v > threshold}| ÷ (max−min+1)

= 45.454545454545

Note

This is a simplified model: it applies the standard probability or game-math formula to the numbers you entered. Real games add pity systems, drop-rate tiers, rounding, server-side variance and balance patches, so treat the result as an estimate rather than a guarantee.
