An Analysis of the Distribution of Birthdays in a Calendar Year – Panix
We can conclude that the number of people with a given birthday is a binomial distribution with mean=n*p=1314.28 (328.57 for Feb. 29) and variance=n*p*q=1313.41 (329.03 for Feb 29). This is a graph of the actual observations with the expected values displayed.

Are Birthdays Normally Distributed? Exploring The Probability …
5 sept. 2023According to statistical analysis, birthdays are, in fact, normally distributed. This means that the majority of people are born on a few specific dates throughout the year, with the remaining days being less popular for births. But why does this happen? Is there some cosmic force at play, or is it simply a matter of human behavior?

Probability theory – Birthday Problem, Statistics, Mathematics
The birthday problem. An entertaining example is to determine the probability that in a randomly selected group of n people at least two have the same birthday. If one assumes for simplicity that a year contains 365 days and that each day is equally likely to be the birthday of a randomly selected person, then in a group of n people there are 365 n possible combinations of .

Here the probability is 365 times 364 times 363 over 365 to the third power. And so, in general, if you just kept doing this to 30, if I just kept this process for 30 people– the probability that no one shares the same birthday would be equal to 365 times 364 times 363– I’ll have 30 terms up here. lesoutrali bot
