True or False?
At a party (of something more than two people), at least two of the people will have the same number
or friends present - true or false?
The Answer is: True. Give labels to everyone in the party which tells how many friends they each have - so
if there sre X number of people at the party, everyone has a label from "0" to "X-1" (the people do not
count themselves). There can not be
a "0" AND "X-1" - if there is a "0" then that person knows no one, and so it is not possible for there to
be a person ("X-1") who knows everyone. With that in mind, there must be a duplicate label since there
are not enough unique labels left.
