A book can be classified as either non-fiction or fiction. Suppose that 96% of books are classified as fiction. (a) Two books are chosen at random. What is the probability that both books are fiction? (b) Nine books are chosen at random. What is the probability that all nine books are fiction? (c) What is the probability that at least one of nine randomly selected books is non-fiction? Would it be unusual that at least one of nine randomly selected books is non-fiction?

### Probability of Fiction vs. Non-Fiction Books

A book can be classified as either non-fiction or fiction. Suppose that 96% of books are classified as fiction. Consider the following probability problems:

---

#### (a) Probability of Both Books Being Fiction

Two books are chosen at random. What is the probability that both books are fiction?

- **The probability is:** 
  - (Round to four decimal places as needed.)

---

#### (b) Probability of All Nine Books Being Fiction

Nine books are chosen at random. What is the probability that all nine books are fiction?

- **The probability is:** 
  - (Round to four decimal places as needed.)

---

#### (c) Probability of At Least One Book Being Non-Fiction

What is the probability that at least one of nine randomly selected books is non-fiction? Would it be unusual that at least one of nine randomly selected books is non-fiction?

- **The probability is:** 
  - (Round to four decimal places as needed.)

- **Would it be unusual that at least one of nine randomly selected books is non-fiction?**
  - It would [dropdown list: select appropriate option] that at least one of nine randomly selected books is non-fiction.
