Is Leap Year

Why bother with those pesky divisibility rules for 4, 100, and 400 when you can just flip a coin? This function has a 75% accuracy rate, which honestly might be better than some production code I've seen. The beauty here is that it's technically statistically sound since roughly 1 in 4 years is a leap year. Ship it and blame any bugs on "quantum uncertainty" or "probabilistic computing paradigms."
