A similar thing is let's say there is 1 million doors - one with a pot of gold and the rest empty.

You are allowed to pick 1 door and you pick a random door. They open all except one door and your own door and ask you "do you want to change?"

Obviously, when you picked a random door, you had a 1/1000000 chance to being correct - they can show you every other door but it doesn't change the odds. The odds of you being correct is still 1/1000000 and essentially, the other door has 999999/1000000 of being correct.

The chances are that you choose a goat(2/3). Keeping this in mind, when they reveal the other goat (and the chances are you have the first one), then if you change you would choose the car. This will only happen if you choose a goat at first, which is more likely. Therefore if it is more likely that you choose a goat first, then it is more likely that when you switch you get the car.
Exactly. I read another explanation similar to yours, and that's when I understood it. :D

21 is the BEST MOVIE EVERThe storyline was EXACTLY what a friend and I are planning to do, before we saw the movie we had a whole plan set up, then when we watched it we were just like HOLY DAMN SOMEONE IS WATCHING USlol
Ha ha. I thought it explained it really well when I saw it in like, 2009 or something. I watched it again yesterday and realised it doesn't really explain it that well :p Nonetheless, it is a good movie.
