    This looks like its homework? See http://forums.codeguru.com/showthrea...ork-assignment

    (a) Give a formula for the probability P (n) that of n randomly selected persons, at least two have their birthday on the same day. Also indicate the derivation of your solution or justify its correctness. You can assume that each year has 365 days (none of them have their birthday on February 29th) and that birthdays are evenly distributed (there are no special events that lead to higher birth rates on certain days).
    (b) Determine the values ​​P (10), P (23), P (35) and P (50) to a minimum of 3 decimal places.
    (c) What did you calculate in this task related to hashing?
