1. **Stating the problem:** We are asked to determine the type of events when considering the events of getting prime numbers and odd numbers. 2. **Understanding the events:** - A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. - An odd number is an integer which is not divisible by 2. 3. **Types of events:** - Events can be mutually exclusive if they cannot happen at the same time. - Events can be independent if the occurrence of one does not affect the probability of the other. 4. **Analyzing the events:** - Some prime numbers are odd (e.g., 3, 5, 7), but 2 is a prime number that is even. - Therefore, the events "getting a prime number" and "getting an odd number" are not mutually exclusive because they can occur together (e.g., 3 is both prime and odd). 5. **Conclusion:** - The events are **not mutually exclusive**. - They are **dependent** because knowing the number is prime affects the probability of it being odd (since 2 is the only even prime). Final answer: The events of getting prime numbers and odd numbers are **not mutually exclusive** and are **dependent events**.
