The famous "Three Door Problem" IQ Test

There are three closed doors on site, behind one of which is a sports car, while the other two doors each hide a goat.

The contestant needs to choose one of the doors; if the contestant picks the door with the car behind it, they will win the sports car.

When the contestant has selected a door but has not opened it yet, the host will open one of the remaining two doors, revealing one of the goats.

Next, the contestant will be asked: will they stick with their original choice or switch to the remaining door?

What is your answer?
