==AutoHotkey Implementation==

The AHK implementation doesn't show percentages relative to each other, it shows percentages total - should it? In any case, it should be pretty simple to change. Also, I can't figure out why the output is so off - is it, or is it just because of the way I did it? [[User:BR|BR]] 18:39, 12 April 2010 (UTC)

I dont beleive everyone else, This is my theory:

ok lets say each O is a door

alright, now lets say each O is a door-

door #'s: 1 2 3

Line 135:

Line 133:

probability: 1/3 1/3 1/3

okay each door has a 1/3 chance; but the two on the left have 66% chance.

okay each door has a 1/3 chance; but the two on the left have 66% chance.correct,

So now say we pick one for example, door 3 ~~okay~~ so we say that it has a 33% chance.

So now say we pick one for example, door 3; awesome possum, so we say that it has a 33% chance of it being a car.

So now we open door ~~one~~ and it's a goat. Now some think that door one still has a 6% chance and door 3 has 33%

So now we open door 2 and it's a goat. Now some think that door one still has a 66% chance and door 3 has 33% chance,

but thats not true because now we only have '''2''' numbers; therefore it's 50/50 chance

but thats not true because now we only have '''2''' numbers; therefore it's 50/50 chance between the two

and i was looking at ~~using~~ this ~~with~~ ~~big~~ numbers ~~like~~ 10 ~~doors~~ ~~so:~~ we ~~have~~ ~~ten~~ ~~doors~~

and I was looking at this and they were using larger numbers to try and explain it, this is what I think:

1 2 3 4 5 6 7 8 9 10

door #'s: 1 2 3 4 5 6 7 8 9 10

O O O O O O O O O O

doors: O O O O O O O O O O

each ~~one~~ has a 10% chance

So each door has a 10% chance

now say we ~~open~~ door 9, at this point, you only have a 1 in 10 chance of getting it right. now next step:

now say we predict door 9; at this point, you only have a 1 in 10 chance of getting it right. now next step:

lets say we open all the doors except for door 7 and door 9 ~~so looking at this problem with all the doors~~ you would think it's in door 7, BUT thats not true now we just have two doors:

lets say we open all the doors except for door 7 and door 9. Now you would think it's in door 7, BUT thats not true now we just have two doors and TWO doors only not 10 but Two:

7 9

door #'s: 7 9

O O

Doors: O O

okay and now they both have a 50/50 chance.

okay and now they both have a 50/50 chance. PROBLEM?

This is what I ~~believe to be true~~, if ~~you~~ ~~have~~ ~~anything~~ to ~~persuade~~ ~~me,~~ ~~please~~ ~~i really~~ don't ~~understand how it's a 2/3 chance~~.

Well then,This is what I think, my friend tells me I'm crazy but I just don't know.
