Math Problem Statement

In how many ways could members of the following club line up all 8 members for a photograph? N = {Jim, Ashley, Emma, Anthony, David, Evelyn, Linda, Craig}

Solution

This problem is asking for the number of ways to arrange all 8 members of a club for a photograph. The members are:

N={Jim, Ashley, Emma, Anthony, David, Evelyn, Linda, Craig}N = \{ \text{Jim, Ashley, Emma, Anthony, David, Evelyn, Linda, Craig} \}

Since all 8 members are to be lined up, we are asked to find the number of possible permutations of these 8 people.

The number of permutations of nn distinct objects is given by n!n! (n factorial). In this case, n=8n = 8.

8!=8×7×6×5×4×3×2×18! = 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1

Let me calculate 8!8!.The number of ways to arrange the 8 members of the club for the photograph is 8!=40,3208! = 40,320 ways.

Would you like further explanation or have any questions about this?

Here are some related questions for practice:

  1. How many ways can 6 out of the 8 members be selected and then arranged for a photograph?
  2. If two members must always stand next to each other, how many ways can the group be arranged?
  3. If the arrangement is circular (for a round photograph), how many distinct ways can they be arranged?
  4. If Jim and Ashley must not stand next to each other, how many arrangements are possible?
  5. How many ways can 3 members be chosen from the 8 members for a smaller photograph?

Tip: Remember that factorials grow very quickly, and even small numbers like 8!8! result in large values like 40,320!
