>Monty Hall asks you if you want to change the door you have chosen. Should you change? And why?

From what I can figure, you have no reason for changing your choice.

When you choose from the 3 doors, you have a 33.3% chance of being right.
After one door is revealed you have a 50% chance of being right.
From what I can tell, you still have no way of increasing your chance of finding the right door.
