Flauer [41]

Answer:

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 first person 365 out of 365 days.
  • 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.

Therefore,

P(4 randomly selected people all have different birthdays)

=\dfrac{365}{365} \times \dfrac{364}{365} \times \dfrac{363}{365} \times \dfrac{362}{365}\\\\=0.9836
