1. A bag containsthreered marbles,fourgreen ones, one lavender one,twoyellows, andsixorange marbles. HINT [See Example 7.]

How many sets of four marbles include one of each color other than lavender?

2.AandBare mutually exclusive.P(A) =.7,P(B) =.1. FindP((AB)').

3.Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containingthreered marbles,threegreen ones,twowhite ones, andtwopurple ones. She grabseightof 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.
