Apr 21 2008 --- Monty's Hall


hmmm ... something which i saw ... kinda interesting ... more commonly known as Monty Hall's Problem ... the beauty of it is that it really sparkles debate within myself on whether or not it is correct or not ... try it ^-^

Imagine that the set of a game that has three closed doors. Behind one of these doors is a car; behind the other two are empty. The contestant does not know where the car is, only the host knows.
The rule is that the contestant will pick a door and the host will open one of the remaining doors, one he knows doesn't hide the car.
After the host open one door which he knows is empty, the contestant is always given the option to switch doors.
What is the probability of winning the car if she stays with her first choice? What if she decides to switch? Does it make a difference whether or not to switch?
