I don't understand what point you want me to answer. Unless you mean:
same with coin flips. anyone who knows anything about probability knows that the longer you flip a coin for, the closer to 50/50 layout of heads/tails you will come. everyone can agree with this. it is mathematically impossible to flip a coin 1,000,000,000,000 times and have more than 60% of either heads or tails. do u see the connection between this and the boy/girl problem?
In which case, yes I do see the connection, but you need to go a step further to answer your own problem. Counting the options is simple and easy, I wrote all of them so the result is obvious if you bother to count up to 4.

just what i wrote...
"lets say instead of 2 children the woman is Mother Earth and she has 8,000,000,000 children. the people who think its 50% and not 2/3 are arguing that even over such a long sample size as the entire planet, there is no tendency towards a 50/50 layout of boys/girls. then how do u explain that this is what happened on the planet earth? the larger the sample size, the less likely it is to be all one gender.

No, you have no argument. The 2/3 answer only works if you eliminate 1/4 of the possible options, whereas you do not.
Where x = all possible scenarios under given facts y = impossible scenarios under x
You will surely agree that scenarios not eliminated = x-y
x = 1- (0.5*0.5) i.e. "The is at least one girl" has 75% chance of occuring y = 0.5*0.5 i.e. "There are two boys" is impossible.
Ergo x-y = 0.5
Sorry :/

again, read what i wrote and reply to it if u really want to reconsider ur opinion. most ppl would rther stick to their first impulse to the bitter end and i can understand that. but the fact is im the one who posted this riddle, and im the one who knows the answer. if u dont want to reconsider thats fine, if u do then read what i wrote and reply to it O_O;

That's completely untrue. You have already flipped coins and therefore those do not count in any future ratios. According to your logic I flip coins 9 times, they all come up tails When I flip the 10th coin, it has a 90% chance of going heads.
Try this yourself. It never works.

Not 90%, but more than 50%. i have tried it, now its ur turn to try ^^;. try it this way: flip the coin 10 times, then 10 more, then 10 more, etc. after each 10 record how many tails and how many heads. over time it will become closer and closer to 50% heads 50% tails. i guaran-damn-tee it. i even have proof: look at the gender layout of the planet. nearly 50% boys and 50% girls. its not a huge coincidence that it happened to be this way now and all throughout history.

Ok I'll make a last try. By saying one of the kids answers, you implicitely create a distinction between the 2 of them. That means BG and GB can not be considered to be the same situation. (kids being ordered by "who answers", instead of their age wich has absolutely nothing to do with the problem) If you can't understand what I mean, I can at least tell you some people (Catyoul and RoTaNiMoD) explained it around page 9-10 of the thread.

Famouzze you only deserve this image: 
Now can we get back to where we were before he derailed it?
|
I am not arguing that if you flip a coin 10 times you will not come closer to 50%. However you are considering the possibility BEFORE established facts.
If it's an established fact that your first 5 flips are 5 heads, then the odds of you coming to 50% tails or above in 5 flips, which was 50% BEFORE your first 5 flips is reduced to infinitisimal odds.
In fact the odds are: 0.5^5.

god i love ppl =) so stupid and yet so sure they're always right =) no offense to anyone! i know its a hard riddle. maybe if u go ask ur math professor? o_O
still waiting for anyone to reply to my post on the terms i laid out. if u really read what i wrote and think it through u will see the light. im also willing to keep replying to try and explain it to ppl who are really making an effort to understand. as it is those are in the vast minority compared to those who woiuld rather be right than be accurate.

Let me put it an easier way. Instead of ranking #1 and #2 in terms of age, lets rank #1 and #2 in the order that you see them. This way there is no possibility of boy-girl switcheroo.
Given: Children are (1,2) 1= Girl
2 Possibilities left:
In order you see them
(girl, boy) (girl, girl)

Famouzze just so you know, you are both wrong and a prick. If you are fine with it, then so be it.

corbalt dude read up on probability theory, it does not work the way u describe the experiment u are conducting stands on its own, it is not affected by previous experiments and it is not dependant on any other previous results(same applies to both coin toss and child sex)
u are taking statistics and applying it to one experiment's probability %, it does not work this way

hey im just telling you, this is the answer. do u really think the person who has known this riddle for years and posted it in the first place doesnt understand his own riddle? i swear to god i know for a fact this is the answer. its not my opinion. take it or leave it as you will...

Now, that looks like a good idea.

I think the person who invented this riddle knows how to word it right. Unlike you.

Wait you know this for a fact Yet so far you have shown your understanding of the subject to be wrong. You can't prove that it's 66/33 and when you try, you get refuted.
So I guess when you prove it, its wrong. When you can't prove it, its right :/

fine lets stop discussing my riddle because its clearly not going anwhere . i'll just post one last thing, the encyclopedia entry for the analogous monty hall problem
http://en.wikipedia.org/wiki/Monty_Hall_problem
if u dont believe wikipedia or cant see the connection between that and the gneder problem then i give up trying to convince anyone.

Nobody said the answer to that problem was not 2/3. It just isn't the same problem, sorry if you fail to understand why. The problem could be analogous if you changed a bit the way you wrote your riddle. But the way you put it, IT IS NOT !
