    I'm not feeling the logic.

    Doesn't the probability reset each time a door is opened? so start 100 doors. all have 1/100. Open a zonk. Now every door has 1/99 chance.

    Fuck, just went ahead and did a visual trial using each combination of 3 and it was right

    I found this to be the best explanation:

    You start out with two goats and one car.
    Monty always eliminates one of the goat doors.
    Every time you choose a goat and switch you win the car.
    Every time you choose the car and switch you win a goat.
    There is a 66.6% chance of choosing a goat on the first pick.
    Therefore switching would win you the car 66.6% of the time.

    The 100-door example really clinched it for me (regarding why the probability doesn't "reset" after each eliminated door). What are the odds you happened to pick the 1 door out of 100 with the car? Far more likely is the 1 door Monty doesn't eliminate.

    This was such a fun watch. I feel like I don't use youtube properly. I watch such trash anytime I'm on there.

    I'm not sure how one would use YouTube properly but I'm sure a high percentage just goes on loops for videos about nothing.
