In probability theory, the birthday paradox revolves around the probability of two people having the same birthday in a set of ‘n’ randomly chosen people. This paradox, along with finding its significance in cryptography today has also featured in various narratives in the past, for instance, in Arthur Clarke’s work, ‘A Fall of Moondust.’
While it may seem far-fetched that in a small group of as many as 23 individuals there’s more than a 50% chance of two people having the same birthday, math, fortunately has it all worked out for us!
Interestingly, the threshold to surpass 50% and reach a probability of 99.9% is quite trivial — in a group of just 70 randomly chosen individuals the birthday problem works it’s magic to illustrate how the probability of two individuals sharing the same birthday shoots up to 99.9%.
Startling, isn’t it? Intrigued? Want to understand this uncanny anomaly better?
