    Different color gum drops are placed into a large black jar and passed around the room. There are 27 pink gum drops, 19 orange gum drops, 12 black gum drops, and 4 purple gum drops. You are the first to pick a gum drop from the jar.

    The probability of  picking purple or pink is 50% (31/62); the probability of picking orange or purple is 37% (23/62); and the probability of picking purple and then is about 1.2% (4/62 X 12/62).
