[Hasbinbad]

yes, definitely.

[Cecily]

Which one poisons the witch?

[Bardalicious]

statistically, yes.. changing to the other bag increases your chances of winning the stone

isn't this common knowledge? lol

[Estolcles]

I stick with the left, only because I suck at stats, and I'm a southpaw, so I'll go with the side life dealt me with.

[Kagatob]

That depends, what race is the person being given the choice?

[Fistandantalus]

Tunare would buckle with all the mod rods i'm summoning laying around.Just Sayin

[Recycled Children]

Tunare doesn't drop the Manastone.

[Lojik]

Tunare or Lunare

[Lu|z Sext]

i met that guy once

still cool as fuck

[Barkingturtle]

Thread would be funnier if instead of three bags she had three holes.

I can't be here all the time to tell you how to post.

[Classic]

Those bags remind me of large loose squirrel testicles.

I would take the one of the left.

[Ahldagor]

kill tunare and open all the bags

[Daldolma]

this was cool in the 70s when anyone still knew who the fuck monty hall was

[Ghost of White Ranger]

lol ur old.

I wrote a program after reading a lot of mathematicians were only convinced after seeing computer simulations. In 9000 trials, switching makes you win ~6000 (2/3), not switching only ~3000 (1/3)

#include <stdio.h>
#include <stdlib.h>

#define MONTY_TRIALS 9000

bool monty_hall_problem(bool switch_doors)
{
bool doors[3] = { false, false, false };
doors[rand()%3] = true;

unsigned int choice = rand() % 3;
return (switch_doors) ? !doors[choice] : doors[choice];
}

int main(int argc, char* argv[])
{
int switch_wins = 0, no_switch_wins = 0;

for (int i = 0; i < MONTY_TRIALS; ++i)
{
if (monty_hall_problem(true)) ++switch_wins;
if (monty_hall_problem(false)) ++no_switch_wins;
}

printf("Switch: %d\tNo Switch: %d", switch_wins, no_switch_wins);

return 0;
}

[r00t]

I forgot to seed rand there but then I did and the same shit happens anyway DUh

[Systolic]

Monty Hall question.

Variable change. Always take the switch. You get an additional 17% equity.

[Recycled Children]

lol ur old.

Says the 35 year old.

[Lune]

You all done fucked up my thread with your slightly higher than average level of knowledge/intelligence/age.

This works much better elsewhere on the internet.

It's amazing how many people refuse to believe that switching improves your odds.

I remember a day at work about 3-4 years ago where a co-worker (a very solid network engineer, not a dude flipping burgers) and I got into a heated discussion about it. He just wouldn't believe it so I made it easy on him and I'll do it for the retards here.

Play out each scenario with the prize being in bag #2. Keep in mind that when Tunare in this case reveals a second bag, it CANNOT be the winning bag. So if you've picked bag 1, bag 3 will be revealed 100% of the time. If you pick bag 3 it will be bag one revealed 100% of the time. If you pick bag 2, it could be either.

You pick bag one and keep it = lose.
You pick bag two and keep it = win.
You pick bag three and keep it = lose.

You pick bag one and switch to bag two = win.
You pick bag one and switch to bag three = cannot be done, revealed as a loser.
You pick bag two and switch to bag one = lose.
You pick bag two and switch to bag three = lose.
You pick bag three and switch to bag one = cannot be done, revealed as a loser.
You pick bag three and switch to bag two = win.

So you can very simply look at this and say, if I stay I have a 1 in 3 chance (33%), if I switch I have a 2 in 4 chance (50%).

Switch every time. Like was stated above, you improve your odds 17%.

Oh, and also this:

It's so funny how many people refused to believe this for so long. It doesn't help an average Joe that so many of the explanations are kinda roundabout and confusing ways of explaining it though, imo.

What's better, people? A 50% chance of picking the right bag, or a 33% chance of picking the right bag? When you make your first pick, you're only getting the 33% chance of being correct. After Tunare reveals an empty bag though, you can either stick with your 33% chance original choice or switch to the 50% chance bag. Derp.

[DrKvothe]

It doubles your chance of being right, actually.

If you switch, the only way you lose is if your initial choice was correct, which was a 33% chance. That means you win 66% of the time when you switch.

All you people saying it increases your odds 17%, to 50% are wrong according to my computer simulation and vos savant herself.

Those who swap always get the opposite of their original choice, so those who swap have 2/3 chance of winning the car (Carlton 2005).


The outcome is fairly obvious from the 1 line of code

return (switch_doors) ? !doors[choice] : doors[choice];

If you switch, you invert your choice. You had a 2/3 chance of being wrong the first time (1/3 chance of winning)

H00t H00t faggot.

[Rhambuk]

all 3 bags are empty because tunare is a lieing bitch.

[Jaxon]

But it's so simple!

http://i.imgur.com/LbxJlsg.jpg

If the manastone is in the bag on the right, choose the bag on the right.
If the manastone is in the bag on the left, choose the bag on the left.
If Tunare is a lying bitch, take all three tink bags and leave.

You are correct by the way the question was phrased. You have a 17% better chance when switching if you select a random option (switch or don't switch). If you always switch vs. never switch then the scenario plays out like your simulation.

Never playing a game of chance with a Sicilian with death on the line.

That or playing a game of chance with a Goddess with a Manastone on the line.
