Possible main combinations = C(N, k) = N! / (k! (N - k)!). With b bonus balls from M, the odds are 1 in C(N, k) × C(M, b).
Example
Inputs: Main numbers to draw = 6, Highest main number = 49, Bonus balls = 0, Highest bonus number = 10, Draw number = 1. Result: Main numbers: 6, 7, 19, 25, 41, 47; Bonus balls: None; Odds of matching all main numbers: 1 in: 13,983,816.
