A box contains 12 marbles of three different colors – Green, Yellow and Blue – 4 of each.

If you were to close your eyes and pick them at random, how many marbles must you take out to be sure that there are at least two of one color among the marbles picked out ?

Just 4 I think. 1 of each color makes 3, then any other marble would make two of one color.
