3 doors
2 goats
1 car

There are three Doors to choose from, and behind them are a goat, a goat, and a car.

By opening one of the doors, and revealing a goat, one of the doors has been removed.

3 doors - 1 door = 2 doors.

And by revealing the goat, one of the goats has been removed

2 goats - 1 goat = 1 goat

Therefore, you are left with 2 doors

Therefore, you are left with a car, and a goat.

You only have one choice to pick between the two remaining doors....

Hence, a 1/2 chance of picking the car.
