The question.......what should you do?

The easiest way to convince yourself of the correct answer (since it's
non-intuitive) is to play the game with someone. After a short while,
you'll realize that the only way you can get it right if you don't switch
is if you picked it right from the beginning - in other words, 1 chance in
3.


Or just play by yourself:

This puzzle right smack dab in the center of my realm, as its a regular
component of one of my classes. I can take you all to school on the solution
on several levels, but I'm not working today so you're off the hook.

MEANWHILE: how about this cherry;

You toss three darts at a target. Dart A misses the target, then Dart B
misses by even more. What is the probability that Dart C will miss by more
than Dart A?
