assuming equal probability for boy or girl

his first kid has a 50/50 chance of either

if the first kid is a girl, then the second must be a boy with 100% likelihood.
so 50% chance you dont have both boys.

if his first kid is a boy then theres another 50% chance that the other one is a boy, but theres no guarantee of either one since we've already satisfied at least one is a boy

so theres a 25% chance that the second kid is a girl and a 25% chance its a boy (this is the only important one since we care about boy-boy).

so its a quarter probability.


But one of the kids is guaranteed to be a boy, so the other one is the only one that matters
50% chance its a boy and you have boy-boy

so its half probability, because probability fucking sucks massive ass and is full of bullshit.
