From the outset the probability of picking the car is 50%. The reason for this is the predetermined nature of the problem.

You see it is a FACT that one door will be opened to reveal a goat and you know that from the outset so situation only has two possible outcomes.

Outcome 1 - The contestants picks a goat
Outcome 2 - The contestant picks a car

Despite there being two goats and one car at the start there is still a 50% chance that the contestant will pick a car.

PREDETERMINED is the key.
