what explanation stands behind "let's make a deal"'s evenement? As i remember there are 3 doors : one with a car behind,and two with goats. After you choose 1 of three doors - they show you one door where there is a goat ,than give you a chance to switch the door and - as my friend claims - you should always switch a door because of the odds but he only read that in some article and cant explain.(adsbygoogle = window.adsbygoogle || []).push({});

How is it more probable that the "switch" is correct choice since it seems 50% chance that you have the right door already?

The only explanation I can see is that you already had one chance and you guessed "right" not taking the one witch the goat they show you , but the switch alone looks still as a fresh 50/50 to me... :(
