If you think about it, always

If you think about it, always picking "switch" makes a lot of sense. When you choose one of the 3 doors, you have a 33.33% chance that it holds the $5 and there's a 66.67% chance that one of the other 2 doors holds the $5. When the computer eliminated one of the 2 remaining doors, that made the likelihood that the last remaining door held the money 66% chance. Therefore, you have a 66% chance of getting the $5 if you always pick switch.
