Question 20 (1 point) Suppose you have 3 red marbles, 2 blue marbles, and 4 yellow marbles in a bag. What is the sample space for an experiment where you pull 2 marbles at random from the bag? Note: "R" = red marble, "B" = blue marble, and "Y" = yellow marble, so "RYB" means that you drew a red marble, then a yellow marble, then a blue marble. 2 ORB, RY, BR, BY, YR, YB ORR, RB, RY, BR, BB, BY, YR, YB, YY 15 ORR, BB, YY 18 ORBY, RYB, RBR, RYR
