Alec campbell of bellevue college writes: i've read about the birthday problem, and how you only need 23 randomly chosen people for there. If n random people are in a room, the classical birthday problem provides the probability that at least two people share a birthday the birthday.
The birthday problem (also known as the birthday paradox) is an example of probability problem where the answer contradicts our intuitions. In probability theory, the birthday problem or birthday paradox concerns the probability that, in a set of n randomly chosen people, some pair of them will have . On examining the drone, they uncovered a device that sought the answer for the so called birthday problem the description of the problem. Tool to calculate the birthday paradox problem the birthday problem is famous in probabilities because its results are non-intuitive it allows answering how. The birthday problem the setting is that we have q balls view them as numbered, 1 ,q we also have n bins, where n ≥ q we throw the balls at random into.
