November 15, 200619 yr 2 of the 3 chests doesn't have the money, if on your first pick you choose one of the 2 empty ones and then you switch your choice you are guaranteed the prize. No, you aren't guaranteed the prize. he would be if he picked an empty one first, then switched, he would get the prize 100% of the time but how he would know which one is empty is another question.... We don't know which ones are empty thats why its a 2/3 chance. But if you happen to pick an empty prize not being aware you picked it and then you switch you are guaranteed the prize. This is alot easyier then when I first heard the situation. Oh well.
