What is the probability of a couple born on the same month and day in China?

About 1 in 400.

There are 365 366 days in a year, and the probability that your wife will also be born on this day is 1 365 after your birthday

This country has not been counted, but this calculation is known, first of all, the husband and wife are the same age and filial piety to find, relatives, friends, classmates, neighbors, and colleagues around 1000 people, there are probably at least 20 people of the same age, and then in these 20 people to find the same month, it is estimated that there are always one or two, and finally look for the same day, this is less, one or two 365 in 2 probability. The worst disadvantage can be estimated like this: only 1 in 1000 people can be 365, which is 1 in 10000 and 1 in 100,000.

Another one out of 1,000,000. In this way, it is possible that only about three out of 1 million people are the same year, the same month, and the same day, and the husband and tenant are the wives, right?

The absolute probability that two people will be born in the same year, month, and day is 1 365;

Probability reflects the probability of a random event occurring. A random event is an event that may or may not occur under the same conditions. For example, from a batch of ** and defective goods, randomly draw a piece, "draw **" is a random event.

Suppose n experiments and observations are carried out on a random phenomenon, in which event a occurs m times, that is, the frequency of its occurrence is m n. After a lot of trial and error, it is common for m n to get closer and closer to a definite posture constant (see Bernoulli's law of large numbers for this assertion). This constant is the probability of event a occurring, which is often denoted by p (a).

In China, the probability of being born on the same day in the same month and year is 1300000000 365*68=52377 (person-days. ）

Suppose two people are born on different months and days.

i.e. (365 365) * (364 365) = 364 365

Then two people born in the same month, then, 1-364 365=1 365

As for the year, since it involves a leap year, you have to look at your year value range. Make a decision again.

It's a coincidence that I met a person born on the same day, the same month, and the same name, just different surnames.

Summary. Hello, I have seen your question and am sorting out the answer, please wait a while How many couples in the country were born on the same day, the same month, and the same year?

Hello, I have seen your question and am sorting out the answer, please wait a while Oh I don't know the specifics but some of them have calculated an approximate percentage.

In the end, it can be estimated that only one in 1,000 people can be 365, which is one in 10,000 and one in 100,000. Another one out of 1,000,000.

In this way, it is possible that out of 1 million people, there are about three couples who are married on the same day, the same month, and the same day.

To calculate the probability that people born on the same day, same month, and same year will be together, the following factors need to be considered:

Distribution of dates of birth: It is necessary to search to understand the distribution of dates of birth, i.e., how many people were born on the same day, month, and day in the population of each year, month, and day.

Assume independence: When calculating probability, it is common to assume that the date of birth is independently distributed in the population, i.e., one person's date of birth is not affected by the date of birth of others.

Algorithms and calculation methods: According to the given data and assumptions, probability calculation methods, such as conditional probability in probability theory, multiplication principles, etc., can be used to calculate the probability that people born in the same year, month, and day will be together.

Demographic data and the associated distribution of dates of birth are required for the calculation method. Because specific demographics and date of birth distributions vary by region and time, it is not possible to provide a one-size-fits-all calculation. If you have relevant demographics and the distribution of dates of birth, you can use probability calculations to estimate the probability that people born on the same day, month, and year will be together.

Hope it helps, hopefully.

The fate between people is very wonderful, and every encounter is a process that everyone is destined to go through. And everyone who is fortunate enough to meet is also drawn by fate. When fate comes, people will naturally meet each other, and they are more likely to unite as husband and wife.

So is it fate for men and women to have the same birthday? Is the same birthday a couple's life?

It is fate that men and women have the same birthday. I believe that many people have a deep understanding that two people with birthdays on the same day and month can meet and know each other when they grow up. But if this happens, it can only be said that this is fate that makes each other meet and get acquainted.

Only fate can connect these two people and make such a rare thing happen.

The same birthday is the life of the couple. Most people with the same birthday have similar personalities and similar preferences, which will allow both parties to have the same interests and hobbies, and then allow both parties to have a deep understanding of each other's topics and become soul mates who talk about everything. Therefore, if a Shenzhou nuclear man and woman born on the same month and day can get to know each other, it is easy to produce a couple of husband and wife.

Although it is not easy to meet the other half, and it is even more difficult to meet the other half who is born on the same month and day as himself, but only by believing that there is fate, the fate of the husband and wife will lead the destined person to meet and unite.
