why in a room with 23 people there’s a good chance 2 of them share a birthday
In: Mathematics
So while people here are commenting on the probability equation, OP should note that the birthday paradox isn’t meant to be “real”, its meant to simply be a statistics problem and fun equation.
In reality, you actually need LESS people than the equation suggests!
Why? Because the equation describes a world where each day has the same likelihood of a baby being born then. However, in the real world, this isn’t the case, and the days differ in significant manners (and will certainly different in different countries and parts of the world too!)
This gets us to a different solution, that is, since people are more likely to be born on specific days, you are more likely to be able to have LESS people needed in the paradox than the simple equation suggests.
