The equation expresses the fact that the first person has no one to share a birthday, the second person cannot have the same birthday as the first ( 364 / 365 ), the third cannot have the same birthday as either of the first two ( 363 / 365 ), and in general the n th birthday cannot be the same as any of the n − 1 preceding birthdays.
This problem arose in a discussion I had with some friends, where we were trying to work out the smallest number of friends you would need so that the probability of all your friends' birthdays covering every day of the year was greater than 50%. I implemented the above formula in PARI-GP with the suggested performance improvements
A birthday attack is a bruteforce collision attack that exploits the mathematics behind the birthday problem in probability theory. This attack can be used to abuse communication between two or more parties. The attack depends on the higher likelihood of collisions found between random attack attempts and a fixed degree of permutations ...
The birthday problem asks, for a set of n randomly chosen people, what is the probability that some pair of them will have the same birthday? The problem itself is mainly concerned with counterintuitive probabilities, but we can also tell by the pigeonhole principle that among 367 people, there is at least one pair of people who share the same ...
Another reason hash collisions are likely at some point in time stems from the idea of the birthday paradox in mathematics. This problem looks at the probability of a set of two randomly chosen people having the same birthday out of n number of people. [5] This idea has led to what has been called the birthday attack.

English: In probability theory, the birthday paradox concerns the probability that, in a set of n randomly chosen people, some pair of them will have the same birthday. By the pigeonhole principle, the probability reaches 100% when the number of people reaches 367 (since there are 366 possible birthdays, including February 29).
