Re: Is competing at multiple regionals REALLY fair ?

It's been a long time since I took statistics. But I think you're logic is flawed.

First, you assume that each team has an equal chance of winning the game. We'll overlook that for the time being.

But each regional is a unique event. If winning is truly random, the chances of winning one are independent of winning another. Therefore

1 regional - 3/50
2 regionals - 3/50 + 3/50
3 regionals - 3/50 + 3/50 + 3/50
etc.
