The chance of: two people
What's the chance that two people share the same birthday? The first person can be born on any day of the year, this means that the probability is 365/365 = 1. The second person has to be born on the same day as the first and there is a 1/365 chance of that happening.
23 people.
In a room of just 23 people there's a 50-50 chance of at least two people having the same birthday. In a room of 75 there's a 99.9% chance of at least two people matching. Put down the calculator and pitchfork, I don't speak heresy. The birthday paradox is strange, counter-intuitive, and completely true.
In probability theory, the birthday problem asks for the probability that, in a set of n randomly chosen people, at least two will share a birthday. The birthday paradox refers to the counterintuitive fact that only 23 people are needed for that probability to exceed 50%.
A word for someone who has the same birthday as you is a "birthday twin." A birthday twin is someone who was born on the same day, month, and year as you. Birthday twins are sometimes considered to have a special connection or bond, as they share the same birthday.
The chance of: two people sharing a birthday would be 1 - (364/365), or 0.3%, or 1 in 370.
The birthday paradox - also known as the birthday problem - states that in a random group of 23 people, there is about a 50% chance that two people have the same birthday. In a room of 75 there's even a 99.9% chance of two people matching. The birthday paradox is strange, counter-intuitive, and completely true.
The probability that a person does not have the same birthday as another person is 364 divided by 365 because there are 364 days that are not a person's birthday. This means that any two people have a 364/365, or 99.726027 percent, chance of not matching birthdays.
December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common. December 24 (Christmas Eve) also makes the list as the 3rd least common birthday while July 4 (Independence Day) is the 4th least common birthday.
If there are 23 people in the same room, there is a 50/50 chance that two people have the same birthday. Sounds a bit surprising, but it's mathematically true! In a room with a certain number of randomly chosen people, a pair of them will probably be born on the same day.
Why the Odds are Actually Much Higher! One person has a 1/365 chance of meeting someone with the same birthday. Two people have a 1/183 chance of meeting someone with the same birthday.
