Now you've loving gone and done it. What's next? Airplane on a treadmill [1]? Rock that God cannot lift [2]?

This is known as the "Monty Hall" problem (the original host of Let's Make a Deal), or alternately oh my god it's that loving thing again kill it with fire.

The puzzle states there are three doors: one of the three always contains a prize and the rest goats (or nothing. It doesn't loving matter what they have as long as it's not what you want).

The prize is put behind a random door and DOES NOT MOVE. You, the contestant, choose a door (any door). We can call this door #1. The host then ALWAYS opens one of the remaining two doors (this door is #2), and ALWAYS shows that it contains a goat and offers you the chance to change your pick to the remaining door, #3.

Should you switch? The answer is yes, you have twice the chance of getting a prize.

Why? When you make your initial pick, you divide the doors into two groups: Virgin and Chad.
The Virgin group contains your one door, so it has a 1/3 chance of being the right pick.
The Chad group contains the other 2 doors, so it has a 2/3 chance.

It makes no loving difference who opens the doors in the Chad group as long as they all get opened, and that's what happens - Monty opens 1 of the 2, you open the other, you thus get 2 shots at getting the prize instead of 1 and so you should switch.

If that doesn't convince you, instead of doing three doors do 1000:

You pick one door, odds 1:1000. Monty opens 998 of the remaining 999 and lets you choose to keep your first choice (1:1000) or open the last one (999:1000). Which one has better odds?

[1] Yes, an airplane on a treadmill can take off as long as the axles/tires can handle a ground speed of |treadmill speed| + |takeoff speed|, because airplanes don't have driven wheels and they don't have the brakes on during takeoff.
[2] A rock filling the entire universe cannot, by definition, be lifted.

Thank you for your service. I didn't want to have to do it again.

This isn't cool at all Looshkin! These are dark forces you're titting about with!

The father of a very dear friend of mine was good friends with Monty Hall. At her father's funeral, Hall approached the coffin to pay his respects, and the lady's husband turned to her and whispered "Tell Monty that I want what's behind the curtain, not what's in the box"

That's my story. Good day.

Am I confused or am I just stupid? Did I unambiguate the quote correctly?

If so I'm still missing the joke. Like I get that's The Line but :confused:

e: Did your friend's husband make a joke about not wanting her father's corpse? It still doesn't work because there's no curtain.

Is the goat the desired prize? I have never seen the show and am also not familiar with the value of livestock.

I'd prefer a goat over a filter coffee machine, but not a speedboat.

Okay, I'm going to ask a question about this that I've always wondered about. We're going to have a short, civil discussion about it, and then move on. If the discussion becomes heated or lasts for too long I swear to god I will carpet-bomb this thread with probations like it's going out of style.

Isn't the answer to this really that it doesn't matter if the airplane is on a treadmill or not, as long as the airplane can get enough speed that air passing over the wing generates lift? Because my admittedly limited understanding is that that's what makes airplanes go up. My confusion about this mental exercise was that I always imagined "plane on a treadmill" as meaning that the plane did not actually move forward; the wheels just kept spinning on the treadmill. No forward momentum = no air passing over the wings = no lift.

Yes, that is the answer. A plane on a treadmill will still take off, because a treadmill will not stop a plane from moving.

The plane can only generate lift if it can reach a thrust angle coefficient of .999... (repeating infinitely). Now, assuming the treadmill is made of well-done steaks rotating around a series of dishwasher-washed cast iron pans, and the plane is full of people wiping standing up, we can determine how much to tip the pilot.

The wheels on an airplane exist to reduce friction with the ground. The wheels spin freely at whatever speed the ground under them is moving and it makes no difference to the airplane.

You need to keep in mind that an airplane is pulled along by its propellor, not its wheels - unlike a car/bicycle, with which you are more familiar.

The wheels exist solely to keep the plane off the ground and - as long as the axles are frictionless - the treadmill has no effect on the motion of the plane.

The only nuance in the question is whether the experiment is taking place in reality or a hypothetical problem space where you don't have to worry about things like friction or material durability, because in reality the wheels would be spinning so fast that you'd either seize the bearings or blow the tires before the plane had a chance to generate lift.

Even if the power were provided by the wheels, as long as they can pull it at enough speed to overcome the treadmill’s backwards pull and move it forward fast enough to get enough air over the wings, it would still take off. It would immediately crash though.
