One of my favorite counter-intuitive facts is that in a group of just 23 people, there’s about a 50% chance that two of them share the same birthday. This is known as the birthday paradox. It seems surprising at first because we might expect that with 365 days in a year, it would take many more people to have a significant chance of overlapping birthdays. The math behind it involves combinations and probabilities that can be quite mind-boggling!
