Question

How many different ways can a committee of 3 republicans, 2 democrats and 1 independent be selected

**Problem Statement:**

*Combinatorial Selection Problem*

There are 6 Republican, 5 Democrat, and 4 Independent candidates. How many different ways can a committee of 3 Republicans, 2 Democrats, and 1 Independent be selected?

**Explanation:**

This problem deals with selecting a specific number of candidates from different groups. It can be solved using combinations, denoted as \( C(n, k) \) or \( \binom{n}{k} \), which represents the number of ways to choose \( k \) items from \( n \) items without regard to order.

1. **Number of Ways to Choose 3 Republicans from 6:** 
\[ C(6, 3) = \frac{6!}{3!(6-3)!} = \frac{6 \times 5 \times 4}{3 \times 2 \times 1} = 20 \]

2. **Number of Ways to Choose 2 Democrats from 5:**
\[ C(5, 2) = \frac{5!}{2!(5-2)!} = \frac{5 \times 4}{2 \times 1} = 10 \]

3. **Number of Ways to Choose 1 Independent from 4:**
\[ C(4, 1) = \frac{4!}{1!(4-1)!} = \frac{4}{1} = 4 \]

**Total Number of Ways to Form the Committee:**

To find the total number of ways to form the committee, multiply the number of ways to select each group:
\[ 20 \times 10 \times 4 = 800 \]

Therefore, there are 800 different ways to select a committee of 3 Republicans, 2 Democrats, and 1 Independent.
