  1. 3 - one red, one blue, one green

  2. There are 2 solutions to this puzzle. The one given is that there are 3 marbles, 1 blue, 1 red, and 1 green. So "all but 2 are blue" meaning that only 1 is blue and the other 2 are not.

    But, you could also have 2 black marbles. Thus, all but 2 are blue (meaning 0 are blue, the other 2 are black). All but 2 are green (meaning 0 are green) and all but 2 are red (meaning 0 are red).
