I can’t tell you how many times I’ve meant to say “Desktop” or “Primary Computer” and have instead said “Primary Desktop”, which indicates I have more than one desktop, which I don’t… People most places look at me liek I’m made of money, which I’m not.. so it doesn’t matter one iota how the information was obtained, so we should assume that all parents with 2 children are collected, and ones meeting certain criteria are chosen. the rest are summarily executed without their child genders being recorded for statistical analysis. we then must surmise the probability that the one unknown child’s gender is either male or female.
