Chapter 8.4, Problem 1E

Recall from Example 1 that whenever Suzan sees a bag of marbles, she grabs a handful at random. In Exercises 1–10, 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 probabilities of the following events, expressing each as a fraction in lowest terms. [HinT: See Example 1.]

She has all the red ones.
