Okay, /g/, we're going to run through a live version of the Monty Hall problem, right here in this ITT thread.
I have 3 files, door1, door2 and door3. In one of them, I have CAR_ followed by 12 random characters. In the other two, I have GOAT followed by 12 random characters.
To prevent me, the host, from cheating by switching doors around, I have sha256sum'd each file: http://pastebin.com/VWaS0aEp
After a door has been selected by 3 posters¸ I will consider that door to be our selection. I will then reveal a goat door, and its contents (you can verify this withecho GOAT############ | sha256sum). Then our choice to stay or switch will be determined by 3 anons, like before.
Hopefully a live simulation such as this will shed some light on the problem, and make the solution easier to grasp.
we're not doing your homework for you, asshole
Always switch doors.
Problem solved.

I vote for door number 1
>>51792576
How could this possibly be homework?

>>51792566
Door 1!
Guys, I think the OP is trying to say he found collisions for SHA256 by changing the random characters, and cheating so we never win.
This is a major breakthrough and will change cryptography as we know it!

>implying running the problem once will convince anyone of anything

Door 4
>>51792642
We'll do it a few times
Door 3
door 5
We just need one more vote, or I could make it the first 2 instead, if there's not enough interest
>Hopefully a live simulation such as this will shed some light on the problem, and make the solution easier to grasp.
The way to explain the problem the best is to use extremely large numbers instead of just 3, thats when it clicked in my brain....
- imagine you have 10,000 doors
- behind one the there is a brand new car
- behind 9.999 of them are goats
- pick one door
- oh, you lucky number - doors #541
- now the host of the show will go and open all at once 9,998 doors
- leaving your door #541 closed and another one lets say #133
- will you switch door?
you now see how obvious it is
you had 1 : 10,000 chance of picking up the right door
but now when its your crappy choice vs the other single door.. its quite obious
>>51792715
I voted for door 2 but I change mine for door 1 ok?
>>51792728
Sure thing Rajeesh!
>>51792615
>>51792639
>>51792728
Door 1 is our choice.
Here's what was in door2: GOATm3kd0akwid2s
Do we want to keep door1, or switch to door3?
>>51792750
switch to door 3
>>51792750
Stay with door 1, I believe in it!
>>51792810
door 3!
>>51792566
>Hopefully a live simulation such as this will shed some light on the problem, and make the solution easier to grasp.
The solution is already easy to grasp if you have more than a moron level mathematics education.
>>51792818
this desu senpai.
Math is a meme anyway
Seems like /g/ might be too slow for 3 anons per choice. Next game we'll go with 2 instead.
>>51792750
door 1
>>51792723
First Choice You have a 33.3.% chance of getting it right.
One door is excluded now your asked again. Picking the other door now has a 50% chance of being right. What is hard to understand about this?
>>51792818
>>51792875
>>51792951
Okay, we are staying with door 1.
Here's what's inside:

Well, how about that? Staying actually helped us, what are the odds?
>>51792975
1 in 3
>>51792975
>math is meme confirmed
>>51792975
1/3
>>51792974
>One door is excluded now your asked again. Picking the other door now has a 50% chance of being right. What is hard to understand about this?
wrong, wrong, wrong, wrong, wrong!
damn i wanted the goat
for sexual intercourse
>>51792974
It's not that easy to grasp as you don't seem to understand it (or are trolling)
But once the host revealed one goat you actually have 2/3 chance of winning if you switch.

New game, new doors.
>>51793012
door 2!
>>51792974
>One door is excluded now your asked again
People need to think of this step as 'All wrong doors except one are opened'
>>51793012
Door 3
>>51792899
Reminder we're only waiting for 2 answers this time
Door 3
>>51792974
low IQ motherfucker right here who have trouble grasping the concept enough to understand why it gives people trouble yet feels like he is some light of knowledge, I bet you suck in school
>Picking the other door now has a 50% chance of being right. What is hard to understand about this?
because people think that not changing the door is the other 50%
large number of doors reveal why its wrong.
>>51792566
Door 3
>>51793040
>>51793072
Door 3 is our choice.
Here's what's in door 1: GOAThsjk93h212ks
Do we want to keep door3, or switch to door 2?
>>51793091
switch to door 2
Door 2
Door three
>>51793028
I think that the best way to understand it is to focus on the initial conditions :
In the beginning, you have 1/3 chance to win,
after choosing a door the host proposes you a new deal :
you can keep your initial choice, or get the TWO other doors and I will clear one of them (as there is obviously a goat behind one of the remaining doors)
Thinking it that way you can clearly see the difference between keeping your choice (1/3) or choosing the 2 others (2/3)
>>51793110
>>51793112
I'm only counting replies quoting the current game now >>51793091
Door three.

Okay, we're switching to door 2

Looks like 50/50 so far
>>51793156
Maybe in a few hundreds of games the theory would emerge

New doors, quote this post or your vote won't count
>>51793074
But there are three doors in the problem, not many doors :)

Hi :3
I'm not doing another one btw
If someone else wants to pick it up, go ahead, just do what I did
