There are still people that think that buying multiple lottery tickets actually lowers your chances of winning.
I tried to argue against someone with this. I even tried scaling the problem down to being two balls drawn from a pool of four, and showing how if you buy multiple tickets, your chances of winning greatly increased. And they accepted what I was saying, but just insisted that the math "doesn't scale" and it doesn't work the same when it's 5 balls drawn from a pool of 69.
Even worse, she tried to say something like "You're really good at math. You should know this!"
