Meanwhile:
Raw probability is about 48.8%. However, if you had both kids with the same woman, the conditional probability will be higher (there are “boy couples” and “girl couples”). Since they could be twins, this also adds a little.
If you live in one of the many countries favouring boys and actively hostile to girls (including in-vitro conception), the probability drops again...
Conclusion: this must be a riddle!
