1. A bag contains three red marbles, four green ones, one lavender one, two yellows, and six orange marbles. HINT [See Example 7.]
How many sets of four marbles include one of each color other than lavender?
2. A and B are mutually exclusive. P(A) = .7, P(B) = .1. Find P((A ∪ B)').
3. Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing three red marbles, three green ones, two white ones, and two purple ones. She grabs eight of them. Find the probability of the following event, expressing it as a fraction in lowest terms. HINT [See Example 1.]
She has all the red ones.
