Answer:
At least 401 chosen guests
Step-by-step explanation:
Represent those with same birth day with Same
So:
Represent number of people with n
There are 365 days in a year and 364 days out of these days is not your birthday.
So, there the probability that n people do not share your birthday is
i.e.
Solving further, we have that:
We're calculating the probability that .
So, we have:
Collect Like Terms
Take natural logarithm (ln) of both sides
Apply laws of logarithm
Multiply through by -1
Solve for n
Reorder
(approximated)
This implies that n = 401, 402, 403 .....
i.e
So, at least 401 people has to be invited
