You absolutely want to switch.

No.  Once he showed a goat, you have a 50% chance of being on the right door. It doesn't matter if you switch or not and it doesn't matter the chance you started with.

Like flipping a coin, its a random walk.  If you flip a coin 5 times and it lands on heads every time, the next coin flip is still a 50% chance that it will land on heads regardless of how many times heads have came up in a row.  Its the same principle.

The easiest way to explain it, at least that I have heard:

There are one million doors and only one has a car, and the rest have goats. You pick a door.

Then the host says, "You can have what is behind your door, or what is behind door 564,238, one of them has the car."

You would be stupid not to switch. You just went from a one in a million chance, to almost certainty.

With three doors, the odds are not as great, but you would have a 33% chance of being right, and then, a much better chance of being right if you switch. You know the eliminated door was a goat.

It is one of those math things that just seems wrong, but it isn't. It is like our brains are not wired to comprehend this simple statistical situation. Also, we want to hold on to our choice, because we made it first, and what we really fear is discovering that we were right all along and second guessed our instincts. In this case though, all the doors are closed so no wisdom or instinct will help us with that first guess. It is just a random guess. The host does you a favor by letting you doubt yourself and guess again.

This is called the Monty Hall problem, you always change doors. I'm sure someones already posted that though, I didn't read past the first sentence

Yeah the natural reaction is to think "well I'd kick myself if it turned out I originally picked the right door". It's possible that you did, but it's twice as likely that you picked the wrong door, and if you did originally pick the wrong door then you are guaranteed the win if you switch.

Chance to choose car out of three doors: 33.33%

Chance to choose car out of two doors: 50%

Chance the first door you chose is the car, after one door is removed: 50%

Really all chances of choosing the right door go up once one door is removed, whether you change or not.

The question is "Is it to your advantage to switch your choice?"

I'd have to say no, since you would still have the 50% chance of choosing the car, whether you decide to change doors or not.

Even though the odds go up for the door that you did not choose, they also go up for the door that you did choose.

What gets people about this problem is the fact that the wrong option shown to you is one you did not pick.

So the chances that you are still wrong stays at 2/3, the chance that the remaining door is right is 1/2

This remains true for any number of doors, but the difference between the odds on your door and the odds of the other doors is less in the favor of switching

No you always switch the doors, look at my earlier post. Your original gander is still tied to the original probability and once a goat is revealed the probability changes, wikipedia Monty Hall problem for a good layout they even have a little excel like chart.

You guys know that 0.999999999 repeated infinitely is equal to one?
Divide 1 by 3 and it gives 0.3333333 to the infinity, then multiply that by 3.

Numbers don't quantize like matter does homies, think about it.

That is why the ultraviolet catastrophe happened I think and statistical thermodynamics get replaced with quantum dynamics.

yes you're first choice is still tied to the original probability, but your new choice, whether it be to stay or not, would be tied to the new probability.

Not switching benefits you only in the unlikely scenario where you originally picked the one correct door, and switching benefits you in the much more likely scenario that you originally picked one of the two wrong doors.

Exactly, and your first choice had a two thirds chance of being wrong, if you don't change the door then you don't change that probability; everything is as it was before the goat was revealed. That last door has 1/2 chance of being wrong and 1/2 chance of being right.

Expanded to 4 doors and your door has a 1/4 chance of being right, the remaining 2 doors have a 1/3 chance of being right. Pick another door.

All of this is similar to why you cannot know momentum and position of particle at the same time. Because the particle is actually existing as a probability across a standing wave

i do see why "the answer" is yes, but i seriously disagree.  Or at least say that it is a question that can be answered both ways.

once one door is removed, one could argue that the first probability becomes irrelevant.

There are still two doors left:

chance first choice was correct: 50%

chance other door is correct: 50%
