5. Use a tree diagram to find the proper compound probabilities.
There are three
possible outcomes: 0 (no yellow candies), 1 (a yellow and a
candy of some other color), and 2 (two yellow candies). FIRST CANDY
SECOND CANDY OUTCOME (bag has 30 candies) (bag has 29 candies)
Yellow (7/29 = .241) 2 yellow = .064
Yellow (8/30 = .267)
Not Yellow (22/30 = .733)
Not Yellow (22/29 = .759) 1 yellow = .203 Yellow (8/29 = .276) 1
yellow = .202 Not Yellow (21/29 = .724) 0 yellow = .531
