Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say Door #1, and the host, who knows what's behind the doors, opens another door, say Door #3, which has a goat. He then says to you,"Do you want to pick Door #2?"

Is it to your advantage to switch your choice?

 

[MattFancy]

Yeah but is that door worth all your blind-bidding money this late in the season?

 

[dickey moe]

Mods: switch to free for all please, thankx

 

[rugcleaner]

yes,

The simplest way to explain it is imagine the same scenario with 100 doors. 98 of them are opened, do you switch to the only other unopened door? Yes, bc it is a 99/100 chance, and the door you picked originally is a 1/100 chance.

 

[IvanKaramazov]

It's half of one and six dozen of the other.

 

[bakes]

is it a female goat?

 

[Foosball God]

is it a female goat?

I'll take door number 3 please.

 

[Officer Pete Malloy]

oh god

 

[heckmanm]

Easiest way for me to think about it is this:

• If you play this game 99 times, you're going to pick the "car" door on your first guess ~33 times.
• This means that you're going to pick a "goat" door ~66 times
• If you never switch, you will win the car ~33 times
• If you switch every time, you will win the car ~66 times

It depends on whether you want a car or a goat and what's behind the door you picked originally.

Pretty simple.

 

[coyote5]

So tell me again why this needed to be revisited??

 

[Dinsy Ejotuz]

The thing that finally helped me with this is...

Original choice = 33% chance you picked correctly, 66% chance you didn't.

The chances remain 66% you chose incorrectly the first time even after they open a door. So the remaining door you didn't choose has a 66% chance of being the car.

WE STILL DON'T KNOW IF HE WANTED A GOAT OR A CAR!

 

[Mr. Pickles]

I would like to know this as well.

 

[Mr. Ected]

Read it wrong...

 

[belljr]

What about the other 1 percent

 

[belljr]

You don't switch. It's 50 / 50 at that point.

 

[Foosball God]

What about the other 1 percent

1 percenters buy their own damn cars.

 

[Politician Spock]

Why do I want a door?

I'd rather have a goat than a door.

 

[Jeremy]

They did an episode of Mythbusters on this years ago. It is an advantage to switch of course, but none of the 20 people who volunteered for the experiment did so.

 

[shady inc]

i don't have any left after spending it all on christine michael

 

[AAABatteries]

Oh, the host knows huh? THAT CHANGES EVERYTHING!

 

[Don Quixote]

Woah. Someone googled "Monty Hall Problem" and found an answer to it on the internet, and then made a video about it and posted it on the internet. The internet is amazing.

 

[SWC]

you wanted a car brohan but you got a goat and no one wants a goat but that hannah chick is one smokin papershaker take that to the bank bromigos

 

[SWC]

what if you switched to the door that was already open and had a goat in it i just blew your minds brohans because some people want to save the earth and believe in goat power take that to the bank

 

[dickey moe]

So tell me again why this needed to be revisited??

Because Vox said so.

 

[dickey moe]

I would like to know this as well.

C'mon, prof.

 

[Juxtatarot]

From Wikipedia:

Monty is saying in effect: you can keep your one door or you can have the other two doors

 

[Tom Servo]

You know, I have a steep hill in my backyard that I have trouble mowing. I think I would prefer a goat to keep the grass down.

 

[TheIronSheik]

Is there an "R", Pat?

 

[dickey moe]

You guys just aren't getting it.

 

[jon_mx]

Also if you are down by 15 late in the game, you go for two if you score a TD.

 

[Peyton Marino]

bin laden had goats. makes u think

 

[jon_mx]

You guys just aren't getting it.

The old answer was pre911 thinking. Never forget! 911 changed everything.

 

[Fennis]

The only winning move is not to play.

 

[Fennis]

yes,

there are only 3 doors

Why don't they explain why it is better to switch in the video? They skipped over that part.

 

[jon_mx]

What if this involved a 15 inch pizza vs. two ten inchers ?

 

[Politician Spock]

Monty used to do this in grade school with candy and a couple of rocks. But when one of his classmates would get a rock they would punch him and take the candy.

Because they don't know which prize the person wants. Weren't you on Jeopardy!?

Sounds like a mass shooting.

Because Vox said so.

Well when do you plan on revisiting it? Do you disagree with the solution? So far all you've done is post a problem that has already been solved and had a giant thread devoted to it.

 

[sbonomo]

Can you just take two goats and call it a day? Think of all the goat dishes you could make!
