Birthday problem

• abstract: In probability theory, the birthday problem or birthday paradoxThis is not a paradox in the sense of leading to a logical contradiction, but is called a paradox because the mathematical truth contradicts naïve intuition: an intuitive guess would suggest that the chance of two individuals sharing the same birthday in a group of 23 is much lower than 50%, but the birthday problem demonstrates that this is not the case. concerns the probability that, in a set of n randomly chosen people, some pair of them will have the same birthday.
