Formula

P(X=k) = C(n,k)·p^k·(1−p)^(n−k)

= 26.6827932

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.
