Ok, assume you pick door number one. There's three possibilities; the car is either behind door number one, two or three. Now:

First scenario, the car is behind door number one. Monty opens door two or three, you switch doors and don't win a car.
Second scenario, the car is behind door number two. Monty opens door three, you switch doors to number two and win a car.
Third scenario, the car is behind door number three. Monty opens door two, you switch doors to number three and win a car.

So two out of three times, you've won a car by switching doors. So you have a 2/3 chance of winnin by switching, or a 1/3 chance by not switching.

Very good explanation, thanks!

I didn't provide the exact numbers, but stated that because the odds are now better for a random selection, is the reason for switching. Am I that bad at explaining 😭
