Question
### Casting Combinatorics Exercise

**Scenario:**
There are 5 men and 8 women auditioning for the school play. Consider the following questions to understand how different combinations of the cast can be formed. 

**Questions:**

1. **If the cast consists of 2 women *and* 2 men, how many different casts can be selected?**

   - **Explanation:** You need to calculate the number of ways to choose 2 women from 8 and 2 men from 5. This involves combinatorial calculations.

2. **If the cast consists of 2 women *or* 2 men, how many different casts can be selected?**

   - **Explanation:** Determine the number of ways to select either 2 women from the 8 women or 2 men from the 5 men. This is an application of the addition rule in combinatorics.

**Symbols for Input:**

- For each question, you will input the number of possible combinations using a numerical input next to the question.

### Note:

This exercise is designed to help understand the basic principles of combinatorics, specifically focusing on selection and combination calculations.
