Read about it last week. The simplest way I can break it down is that if you stay with your choice, you only open one door on the three. If you switch, it's as if you opened two doors. Another way to see it is that you have 2/3 chance that you picked the wrong door, 1/3 you chosed the right one. If you picked the wrong door, switching will win.
