We have met couples that have birthdays that are close to one another but not the same day.
The chance of: two people sharing a birthday would be 1 - (364/365), or 0.3%, or 1 in 370.
That's what you get when you are playing the birthday game with the ratio of 1/365. Surely it gets more complicated with couples. “Not so,” says Professor Rosenthal. “The 1/365 is still in play and the odds are that one in every 365 couples share a birthday.”
It's certainly a rarity. Statistically speaking, with 365 days in a year, there's a .27 percent chance of any two people sharing the same calendar date as birthdays .
Cassidy and Dylan Scott, a married couple from Huntsville, Alabama, just happen to have the same birthday.
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%.
The birthday paradox, also known as the birthday problem, states that in a random group of 23 people, there is about a 50 percent chance that two people have the same birthday.
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.

Since there are 363 days still “unused” out of 365, we have p = 363÷365 = about 0.9945. Multiply that by the 0.9973 for two people and you have about 0.9918, the probability that three randomly selected people will have different birthdays.
