I recently purchased a ticket for Spain’s christmas lottery. For those that don’t know how it works: they use two large drums for this. One contains all the participants numbers, the other the prices. There are multiple prices that one can win with different values. As the game went on, my number wasn’t called, neither for the big prize nor for the multiple small ones. I said to my family that this was good, as it meant that the odds of getting the large price were greater than at the beginning of the game. My logic was that since numbers can’t get two prices, the numbers that got small prices were out of the race, meaning less balls in the drum with participants but with the big price yet to be given. My sister, who attended university level statistics classes said I was wrong and that the odds were the same, but she didn’t want to explain why because it was too complicated. Can anyone here please explain where I fucked up with my maths?
