There are 5 green,5 red, 5 bue . and 5 yellow hats. How many hats should be pulled out to be certain to have at least 4 of one color?

OpenStudy (lgbasallote):

if you pull 5 you're sure to have two of the same colors...does that help?

OpenStudy (anonymous):

I dont get it XD

OpenStudy (lgbasallote):

if i pull 5..since there are only 4 colors..then the 5th is bound to be one of the 4 right?

OpenStudy (anonymous):

yeah
