The following table shows the probability for some other values of n (for this table, the existence of leap years is ignored, and each birthday is assumed to be equally likely): The probability that no two people share a birthday in a group of n people. Note that the vertical scale is logarithmic (each step down is 10 20 times less likely).

The probability of an event is a number between 0 and 1; the larger the probability, the more likely an event is to occur.

A study using the populations of Denmark and Austria (a total of 2,052,680 deaths over the time period) found that although people's life span tended to correlate with their month of birth, there was no consistent birthday effect, and people born in autumn or winter were more likely to die in the months further from their birthday.

If an ace is drawn from a deck and not reinserted, the next card drawn is less likely to be an ace and more likely to be of another rank. The probability of drawing another ace, assuming that it was the first card drawn and that there are no jokers , has decreased from 4 / 52 (7.69%) to 3 / 51 (5.88%), while the probability for ...
Some say it started in ancient Roman times when flowers were often gifted as a way to celebrate birthdays. Others attribute the custom to the Victorian era when flowers were often given meaning ...
Throughout history, societies have had numbers they consider special.
