When probability meets confusion! The first guy thinks the Tuesday detail creates a conditional probability problem (2/3 or 66.6%). But wait—the second guy correctly points out it's just 51.8% (roughly 50/50 gender odds).

The Tuesday information is completely irrelevant! It's a classic Bayesian trap where our brains desperately try to incorporate every detail into the calculation. The day of birth has zero impact on gender probability—yet our pattern-seeking minds get bamboozled anyway.

Next time someone tries to trick you with extra variables, channel your inner statistician and ask: "Does this information actually matter to the outcome?" Usually not.
