I still don't get it, "changing your choice."
21 is on, you know the old situation where you're given three choices, you make your choice, then one of the incorrect options is eliminated, and the question is whether or not it benefits you to change your choice.
The answer is yes, apparently. But why?
I asked a friend in support of the answer "what if I change it, and change it back?" and he says that this also gives me the benefit. What? That changes nothing regarding the probability other than the words I spoke to change my choice twice.
As far as I can tell, once the third, incorrect option is eliminated, it becomes 50/50 probability regardless of whether or not I change my choice.
Can someone explain?
