Solution to: Bizarre Boxes
No, there is no reason to change your choice.
An explanation: The hint provided is misleading! In this puzzle, it is not straightforward to calculate the expected value as suggested in the hint. Therefore, just use your common sense and note that there is still a 50% chance that your first choice is the best one. There is no reason at all to change that choice once you find out that the box contains $10.
