A jar has eight red, nine blue, and ten green marbles. What is the least number of marbles that you can remove from the jar and be certain that you have three of the same color?

you would subtract 3 from each colour which would give you 5 red 6 blue and 7 green and all those added up would be how much marbles you should take in total to give you 3 of the same colour
