What is the probability that two out of ten people will be born on the same day?

I'll give you a hint and think about the rest.

One thing that can happen to ten people is: 1. Ten people are in the same Amanome2. There are nine situations in which nine people are in the same Amanome. If expressed in language, it is C 10 and 9; 3. There are 45 cases of 8 people in the same ointment, which are C 10 and C 8； respectively; 4. Seven people are the same Amanome, which is C 10 and 7; 1 1. There is only one case where zero people live in the same Amanome.

See if it's right. Ask me if you have any questions.
