Show the formula
Chance of catching exactly 10 of your 10 spots when 20 numbers are drawn from 70:
P(10) = C(20,10) × C(50,0) / C(70,10)
= 184,756 × 1 / 396,704,524,216 = 1 in 2,147,181
C(n,k) is the number of ways to choose k numbers out of n. The first factor picks which drawn numbers are yours, the second picks your other spots among the numbers not drawn.
