    Assuming Monty always gives a choice when you choose the car, and those choice opportunities happen twice as often as choices when you have a goat:

    pick the car: 2/6
     - new choice: 2/6
        - stay and win or change and lose
    pick a goat: 4/6
     - new choice: 1/6
        - stay and lose or change and win
     - no new choice: 3/6
        - stay and lose

    Results: Stay and win 2 times in 6. Change and win 1 time in 6.
