Door A | Door B | Door C |
—————————————————————————-
Car. | Goat. |Goat.|
Goat. | Car. | Goat.|.
Goat. | Goat. | Car.|.
The above tables shows all possible distribution of car and goats. If the initial choice was Door A, then you only have 1/3 probability. But after B/C door is opened the probability increases to 2/3 if switched.
The clue is that the host will always open the door with a goat.
