![**Permutations of Three Items from a Group of Six**
To determine how many permutations of three items can be selected from a group of six, follow the steps below. This exercise will help you understand permutations and how to list them systematically.
**Problem Statement**:
How many permutations of three items can be selected from a group of six?
**Instructions**:
1. Use the letters A, B, C, D, E, and F to identify the items.
2. List each of the permutations of items B, D, and F.
3. Enter your answers as a comma-separated list.
4. Enter three unspaced capital letters for each permutation.
**Steps to Solve**:
1. **Identify the number of items and the group size**:
- Total items: 6 (A, B, C, D, E, F)
- Number of items to select: 3
2. **Calculate the permutations**:
- The formula for permutations of selecting \( r \) items from \( n \) items is:
\[
P(n, r) = \frac{n!}{(n-r)!}
\]
- For this problem, \( n = 6 \) and \( r = 3 \):
\[
P(6, 3) = \frac{6!}{(6-3)!} = \frac{6 \times 5 \times 4 \times 3!}{3!} = 6 \times 5 \times 4 = 120
\]
- Thus, there are 120 permutations of choosing 3 items from a group of 6.
3. **List permutations of B, D, and F**:
- For three specific items (B, D, F), generate the permutations:
\[
\text{BDF, BFD, DBF, DFB, FBD, FDB}
\]
These permutations are important in helping understand how arrangements are made in different scenarios, whether in mathematics, computer science, or organizing physical and digital objects.
**Optional Show My Work Section**:
- Use this section to detail the steps and reasoning you used to find the permutations.
- This can help in gaining a better understanding, and may also earn bonus points.
