PROBABILITY PROBLEM!!!!!! HELP!!!! A game show host has a selection of 3 doors. Behind one of the doors is a brand new car and behind the other two are goats. The host tells the contestant to pick a door. Once the contestant has picked the door, the host reveals another door which contains 1 of the 2 goats. The host offers the contestant the option to switch his door and the contestant refuses because he now has a 50% chance of winning the car. Is the contestant right to stay with his door?

I'm confused, would it make a difference if he switched doors? Regardless he still has a 50% chance since there are only two doors left?

Well yes because he has a 50% chance of winning...But he also has a 50% chance of losing...this is a very tricky question!
