No, this problem is different, and has a different solution. In your problem it makes sense to switch when given the choice, whereas in this one it does not. With the three doors you're given additional information once you choose a door, which allows you to choose a door with 1/2 probability of being right, rather than the 1/3 chance you started out with. In this problem you are given no additional information, so the probability of choosing the right envelope is the same when given a choice to switch as it is at the beginning (i.e., 1/2).
- mirkules 16y agoActually, your probability of choosing the right door is 2/3 if you switch. I agree though that this problem is not the same, it just reminded me of it -- I guess you could say it's a similar class of problems.
