I never knew this was called "Monty Hall"

Several years ago I walked into an office with a group of guys having an animated argument over a game on a white board.

"Pick one of these doors" (drawn on the board). "If I tell you there's a brand new car behind one of them, then after you make a choice, I'll tell you which one of the remaining doors is incorrect, should you change your choice to the other remaining door?"

So you could be right all the long, but you now know a little bit should you change.

I've since bought this up at other offices, dinner parties, BBQs etc and wonderful conjecture always ensues.

Anyway, I found an online version - here - - check it out. You should win this, 66.666% of the time.
