The birthday problem can be generalized as follows: Given n random integers drawn from a discrete uniform distribution with range [1,d], what is the probability p(n; d) that at least two numbers are the same? (d = 365 gives the usual birthday problem.) [15] The generic results can be derived using the same arguments given above.
The name is based on the birthday paradox. Choose m birthdays in a year of n days. List the spacings between the birthdays. If j is the number of values that occur more than once in that list, then j is asymptotically Poisson-distributed with mean m 3 / (4n).
Cheryl's Birthday" is a logic puzzle, specifically a knowledge puzzle. [ 1 ] [ 2 ] The objective is to determine the birthday of a girl named Cheryl using a handful of clues given to her friends Albert and Bernard.
A naive application of the even-odd rule gives (,) = = () ()where P(m,n) is the probability of m people having all of n possible birthdays. At least for P(4,7) this formula gives the same answer as above, 525/1024 = 8400/16384, so I'm fairly confident it's right.
Bertrand's box paradox: A paradox of conditional probability closely related to the Boy or Girl paradox. Bertrand's paradox: Different common-sense definitions of randomness give quite different results. Birthday paradox: In a random group of only 23 people, there is a better than 50/50 chance two of them have the same birthday.

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.
In the earlier version of "Rumpelstiltskin," The Miller's Daughter has a perplexing, but empowering problem, she can only spin straw into gold, and is unable to complete her needed domestic duties. In the now popular 1812 version of "Rumpelstiltskin," The Miller's daughter is forced to spin straw into gold by a greedy king, but continually ...
