Birthday problem explained

It's a mathematical equation that proves in a group of 23 or more people, at least one pair will have matching birthdays. Humans think in linear terms so they believe the odds to be very low. However, chance is exponentially increased - so the odds are much higher. With just 23 people the chances are 50% that 2 people will have matching birthdays.If you aren’t familiar: the birthday problem, or birthday paradox, addresses the probability that any two people in a room will have the same birthday. The paradox comes from the fact that you reach 50 per cent likelihood two people will share a birthday with just 23 people in a room. With 70 people you get to 99.9% likelihood.
