It's just psyhology and math all togetherIf u remove 33,3% leaves u with 66,6% chance that one of those 2 left is the good one, if he tells u to change, he just tests u, and most people choose to stay, but if u change it, u purely do what he wasn't expecting, do what he says.Most people don't wanna do what some1 tells them to do, so he tells u that, to make u feel more confident about ur door.In the end, if u change, u just get a higher chance of geting the prize, i can't explain it as i really believe since my english isn't good enough for me to say all i'd like to.In general, i'd change because humans tend to do what they are not told to. If he tells u to switch, he just tries to make u stay at the same door as u are. Hope that what i've said made any sense, if not, sorry.
Assuming you can ask him questions, ask him where is the right door and where is the wrong door - then let him talk the whole show and count how many times he says the name of each door - the one that has been mentioned the most is probably the one with the car.
1/3 - Probability of getting car.1/2 - Probability of getting car after first door is opened.1/2 - Probability if you change.
For people that don't like reading a lot: 9 ScenariosHost will always open one goat door.
This is retarded and not even mathematical, why would you exactly switch from C to B instead of C to A, you just made 66.6% of all switches a win, while ignoring the fact that there are 3 doors, not 2. GTFO, this is bullshit.Ignore that post ^ I didn't read OP's post right, he said the man would open the door with the goat first and show you that there is a goat and then ask you... This is just stupid, the whole point of this post is to read carefully.
