> If you have a choice to make between two doors, then the odds > must be 50:50 As a catch-all statement that is (of course) nonsense. If you have a choice between two doors, but know there is no car, your odds are 0:0. If there are two cars, the odds are 1:1. If I am honest and I tell you where the car is your odds are 1:0 (or 0:1). So you realy must do some thinking, applying gut-feeling won't work. Of course it won't, this case gets so much attention *because* gut-feeling 'logic' does not work here.
