You choose 1 door and can either switch or stay. That yields 6 possibilities

Choose A + Stay = Win
Choose A + Switch = Lose
Choose B + Stay = Lose
Choose B + Switch = Win
Choose C + Stay = Lose
Choose C + Switch = Win

As you can see, switching gives you 2/3 winning while staying gives you 1/3

Also can be thought of variable change.

But, now a door is gone. Let's say you chose door A and he opened up door C. You still have no idea what is behind which door. He you have two choices. Stay or switch, 50-50 chance of selecting it right. EDIT: Once one door was opened a new factor was introduced completely changing the problem.
