Whats the chances of it being a girl?

Asked by sandystrachan (4417points) June 5th, 2009

As you may know we are having our 3rd baby, Whats the chances of it being another girl . Our other two children are girls , her sisters kids are all girls . Does that mean her baby maker is a higher chance it being another girl , or could it be just my baby makers that make girls ?

No, the existence of other children does not statistically change the probability of the next child’s gender, because the events are independent. The probability is around 49% chance of it being a girl.

You can also take a lot of quizzes on the internet, apparently (with varying degrees of reliability) to find out a more precise probability based on your specifics.

I always find this interesting. Statistically, it’s about even chances, but in any given family it sure does seem different. In his family, my ex-husband’s generation was all boys except 1 girl. My kids generation of this family is all girls except 1 boy. For what it’s worth, we had three girls and couldn’t be happier.

Chances of having a boy after 2 girls = 46%

Independant observation: @La_chica_gomela did not cite sources for her first comment either…

It’s complete randomness. Your chances are no different than they were for the first child.

@benseven: I’m not questioning @YARNLADY, or trying to assert that all comments should have sources. I’m actually just wondering where she got that figure.

@dynamicduo – It might not be entirely random. There are several scientific studies investigating the issue. Here are some statistics provided by the CDC:

Here’s also some interesting background information

I thought it was just 50/50. I didn’t know more statistics were involved.

I know with us, girls usually come first for the men in my husbands family…but, we had a boy first.
Are you hoping for a boy?? They really are so much fun. I’m sure if you have another girl it’ll be a walk in the park, what’s one more female! hehe

Not really bothered its sex as long as its healthy .

casheroo's avatar

True. Are you and your wife going to find out ahead of time, or let it be a surprise?

Just in case you aren’t aware of this-

It’s the male parent that determines the sex of the offspring. The female parent can contribute only an X chromosome, the male can contribute X or Y. If he contributes an X, you get a girl. If it’s a Y, you get a boy.

They don’t inform you of the sex here :( we tried getting told with our 1st two . We would love to find out the sex so we can get more things ready

casheroo's avatar

They don’t let you find out? That’s no fun. I watched the 20 week ultrasound and knew it was a boy before they even said it. Boys are easier to identify on the screen.

sandystrachan's avatar

Yes they don’t tell you the sex .

hm….i think there is a way to figure it out mathematically.
i think there was a problem like this in my stats book.
but i took that class like, 2 yrs ago and don’t remember anything…

That’s what’s so maddening about randomness—you really just can’t tell what comes next. Although maybe in the case of lots of babies for one couple of one sex or another, there is something about the soup in which the baby is made that favors one sex or the other. My guess is it’s still about 50–50.

La_chica_gomela's avatar

@amoreno06: That’s incorrect. Please read my link on the statistics definition of “independent”. If there are any clues as to the sex, they will be found in @mattbrowne‘s links and in that type of information generally, not in mathematics.

@Triiiple: If you read @mattbrowne‘s third link, you will find out that that’s actually incorrect also. In the human population, the probability of having a boy is slightly higher than that of having a girl, as I wrote in my first answer.

@La_chica_gomela I googled chance of girl after 2 girls
I usually try to provide sources, but I got in a hurry on this one. I believe in sources.

La_chica_gomela's avatar

@YARNLADY: Thanks! That was actually really interesting. Since you just linked your google seach, and not an actual webpage, I’m assuming you looked at the the first hit, so I did too. Really cool stuff.

YARNLADY's avatar

@La_chica_gomela I looked at several of them, which is why I linked the whole search list, and many gave the same number, but could have been from the same orginial source.

amoreno06's avatar

@La_chica_gomela that’s why i only said i think.
i’m no math whiz.
and i’ve got the memory of…idk what exactly. i can’t remember right now.

Update It’s a…....... Click to fond out :P
