The way I finaly convinced my brother:

If you DONT switch --- You win if your first pick is the correct door (1 out of 3)

If you DO switch --- you win if your first pick is either if the wrong doors. (2 out of 3)

Dont see how it works?

Lets pretend the prize is behind door (A). Now lets see what happens when you pick each door.

You pick door (A):
Monty opens door (B) showing the Donkey.
You change to (C) - You lose.
(or he could show door (C), and you change to (B) and still lose)


You pick door (B)
Monty opens doos (C) showing the Donkey.
You change to (A) - You win.

You pick door (C)
Monty opens doos (B) showing the Donkey.
You change to (A) - You win.
