### Probability Exercise

**Question 92**

Given that the universal rules and the below data hold:

- \(P(F) = 0.28\)
- \(P(G) = 0.12\)
- \(P(F \text{ OR } G) = 0.33\)
- \(P(F \text{ AND } G) = 0.07\)

**Tasks:**

a. **Explain why the following statement MUST be false:**
- \(P(G \text{ OR } H) = 0.5\)

b. **Find \(P(G \text{ OR } H)\) if \(P(G) = 0.3\) and \(P(H) = 0.4\).**

c. **Are G and H independent or dependent events? Explain in a complete sentence.**
