There are three doors in front of you.

One of the doors has a car behind it.

The other two both have goats behind them.

Monty doesn’t know what is behind the doors.

You pick a door.

Monty randomly opens one of the other doors and reveals a goat.

Monty give you the option of sticking with the door you have picked, or switching to the unopened door.

Same solution?

The simplest way I can think of explaining it is:

You have 2 options, switch or don’t switch.

Switch- you win when either of the two other doors hide the car. Don’t Switch- you win only if your original door has the car.

The only other thing to add is- a surefire way to win is to pick the door Monty reveals has the goat. Then you will 100% get what you expect.

Pick a better brain teaser ;)

However, maths aside, I wouldn’t switch because conviction is easier to defend than doubt. (You know, if I was wrong and ended up with a goat)
