A person's initials are two letter in a specific ordr. If everyone has initials, what is the fewest nu,ber of people who must attend a party to be sure the three of the people will have the same initials?

This is known as the pigeonhole principle


There are   (26)(26) =  676  possible sets of initials


Let's suppose one person has the initials  JG


We might have to go through a total of 676 more people to find another person with the same initials


And we might have to go through another set of 676 additional people to find the third person with the same initials


So  ....1 + 676 + 676  =  1353 people will guarantee three peope with the same initials
