Birthday Paradox deals with the probablity that there are at least two people having the same birthday within a group of q people. According to Birthday Paradox, this probability is 0.5 if q equals \sqrt{365}~.

More generally, if there are N possible values for output value the collision probability grows roughly proportional to \sqrt{q}/N~.
