Step-by-step explanation:

There are 365 days in a year.

Since each person has a different birthday:

We can choose a birthday for the second person 364 out of 365 days.
We can choose a birthday for the third person 363 out of 365 days.
We can choose a birthday for the fourth person 362 out of 365 days.
