The Odds: Gender Edition

1 Apr

“Are you finding out what you’re having?”

Boys? Girls? Eh?It’s not an issue I covered in the FAQ because it honestly didn’t occur to me it would even be a question.  But friends have asked and cripes, yes, definitely, we are finding out the genders, tout suite. The births day will be insane enough without throwing Dancing With The Stars-style reveals into the mix.

The gender-unveiling could happen as early as a few weeks from now and we’re beyond anxious.  We’ve heard stories about modest fetuses that refuse to let their parents know, ultrasound after ultrasound.  Fingers crossed for three little exhibitionists.

Anyhow, I started doing a little math, because I’m a sucker for things like odds and research.  So here goes:


  • All three babies will survive delivery and beyond
  • The triplets are not identical
  • Gender-bending oddities like hermaphroditism has been discounted
  • Ratio of boys to girls under normal circumstances = 1:1

Okay, that said, odds of a single-child pregnancy (you know, the way normal, sane people do things) is pretty straightforward:

The Odds: Single Child

Non-identical twins. Slightly more complicated, but not much:

The Odds: Twins

Triplets?  I had to grab a pencil and paper for this one and break down each possibility, of which there are 8.  As follows:

That said, we have 4 basic combinations with odds that look like this:

The Odds: Triplets

Chances of at least one girl: 87.5% At least one boy: 87.5%

The odds seem to sharply favor a combo, but I guess we’ll see.  It’s what Carey prefers (her ideal is 2 boys, 1 girl).  Me, I don’t know.  I suppose I’d like to have a son somewhere in the mix.  I think we’re in agreement that all three being the same gender (25% chance) probably isn’t what we’d want most… though, I’ll admit it, when we first got the news, all one gender was my preference.  “Stick ’em all in one room through high school.  Boom, done.”

But here’s where we do our classic parent-to-be refrain (I think they take away your permit if you don’t repeat it at least a couple of times a week).  All together now, people:


(But c’mon, Jesus, do us a solid and throw a boy in there for us, would you?)
