A woman has two kids. One is a boy. What are the odds the other is a boy?

So there's about twice as many females on the planet compared to males?

I wish that was true, though.


I've heard somewhere that there's a 50.5% chance of getting a boy because newborn boys die more commonly than newborn girls. Though I don't recall any sources to this.

It's like scrolling a weapon with a 30% scroll in-game, you tell me. ;]
