Question 64572
A boy has 3 red marble in his pocket, 4 blue marbles, and 4 green marbles. How many will he have to take out of his packet to ensure that he has one of each color?
------------
He could pick 3 red, then 4 blue. The next marble must be green and he will
at least one of each color.  # of picks= 3+4+1=8
