Popis:	SummaryWe present a simplified derivation for obtaining asymptotic approximations of the expected number of people needed to find two with the same birthday in a year with a specified number of days. This derivation of an expected value in the birthday problem uses only techniques common to a standard calculus course and avoids higher-level methods used in previous derivations.
