the monty hall problem is absolutely bullshit. the odds between the door you picked and the door you didn't are the same, they don't magically have different odds just because you picked one prior
you pick A. B is shown to be false, so you're given the choice between A and C. A and C are both still unknown to you and thus have equal odds. A no longer has a 1 in 3 chance, because there's only two doors to pick from now.
sorry, but none of you can convince me that this isn't some sort of fucked up maths major in-joke or hazing thing
Yeah, I feel like every explaination out there is for boomers/americans who know who Monty Hall is (not even a mathematician) and have watched a bunch of whatever gameshow the problem references, and already know the rules of the game being played, so they don't explain them very well.
It's like if I mathematically prove that running sideways around your target in a circle while shooting at it is mathematically optimal in terms of avoiding return fire and being able to hit the target, telling everyone they're wrong and going over the maths again if they say I can't run like that or that bullets are too fast to dodge, without mentioning I mean in Quake 3.
(also the problem also says that you know he knows the prizes and the effects that has on his choices, but not that he knows that you know that he knows, and intuitively you would think he might bluff, which is usually an unwritten rule of explanations of the problem that he's not playing against you, he's following a script. I assume that's because that's how the gameshow goes?)
