What if there were three colors of marbles in the bag, how many would you have to pull out to get two marbles of the same color? Three? Four? Generalize by finding a formula for predicting the number of marbles you would have to pull out to get the same color of any amount you desire.

That should start you out in getting your formula. Let c = number of colors and n = number of marbles you want of the same color.
