Jeremy and Noor are playing a game where they each draw a marble from a bag, and whoever draws the marble worth the most points wins. Red marbles are worth 1 point, green marbles are worth 2 points, blue marbles are worth 3 points, and white marbles are worth 10 points. There are 4 of each type of marble in the bag.
