This math is wrong wrong wrong if they hope to keep people thinking they have a clue of what they are talking about. Let’s look at it from a wick dipping perspective(AKA reality) I have a boy who was born on a Tuesday. Then I dip my wick again. 50/50 chance of a boy. Full stop. 50% boy 50% girl. Wait 10 months dip again. 50/50 never changes unless you have a IVF clinic screwing around. Stats might skew this a bit towards boys but that is biology not math.

They are trying to use the same shit as used on the Monty Hall problem.
