You can sume that anyone you ask is equally likely to be born on any of the 365 days of the year (we will hore February 29 birthdays - sorry if you are a leap year baby!). Let's define A, to be the event at you must approach more than n people to find someone with your birthday. The smallest lue of n such that P(An) is less than 0.5 is:
