The following probability tree diagram shows tossing an unfair coin FOLLOWED BY drawing one bead from a cup containing 3 red (R), 4 yellow (Y) and 5 blue (B) beads. For the coin, P(H) = W N and P(T) = where H = "heads" and T = "tails". R 3/12 Y 4/12 2/3 H B 5/12 R 3/12 T 1/3 Y 4/12 5/12 B Find P(Blue bead): O 15/36 10/36 O 10/12 6/36
