·with all these birthdays on the zone lately, i remebered an old question in math class.

How many people have to be together in a group, in order to have a bigger chance of birthdays falling together, than the chance of having all unique birthdays?

In other words, how many people should there be so that it is LESS likely to have a unique birthday than one together with another member of the same group?

All of those who had statistical math in their early days, break out the calculators! :laugh

cheers, jan
