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
