The answer should be 99.99997%.
This is the birthday paradox, where 23 people is 50%, 70 people is 99.9%, and 367 people is 100%(Feb 29 does count.)

Um, this not might be correct cause I’m a much lower grader but,
How many odd numbers in 100:
I’m just guessing like it is like this...
Number of odd numbers in a 100 is 50.
So 50 people have the same birthday as you.
