1) Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing four red marbles, three green ones, two white ones, and one purple one. She grabs five of them. Find the probability of the following event, expressing it as a fraction in lowest terms. HINT [See Example 1.]

She has two red ones and one of each of the other colors.

2) 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 three purple ones. She grabs seven of them. Find the probability of the following event, expressing it as a fraction in lowest terms. HINT [See Example 1.]

3) The local diner offers a meal combination consisting of an appetizer, a soup, a main course, and a dessert. There are fourappetizers, five soups, four main courses, and four desserts. Your diet restricts you to choosing between a dessert and an appetizer. (You cannot have both.) Given this restriction, how many three-course meals are possible?

You have a bag of marbles. Your bag contains 75 marbles. You only want the red marbles. You know that 30 of the marbles in the bag are red. You randomly select two marbles from the bag and set them aside without looking at them. Let X represent the number of red marbles removed. (hint. This is without replacement.) a) find the probability mass function (i.e. probability distribution) for the number of red marbles selected. b) find the expected number...
