First I ask the question: "What is the largest number of marbles I must pick
and still have the possibility that I don't have 7 of the same color?"
green 13......6
red...10......6
blue..9.......6
yellow 8......6
black..6......6
whitee.4......4
If I happened to pick these colors in the indicated numbers, I still
wouldn't have 7 of the same color
But if I pick one more, I am guaranteed to have 7 of the same color.
The answer is 35
