what if you had to pick 6 balls out of 49 but the catch is that lottery will pick more than 6 numbers. lets say 10 balls for example. A real example is New York's pick 10. You have to pick 10 out of 80 balls, but they pick 20 balls. You win if your 10 are in that 20. What is the formula for that situation??? CraigGuitardart (talk)
