Anh, Bryan, Carol, Dan, Elise, Felix, Harry, Joy

In how many different ways can the director choose the members for the show? (The order the members are chosen doesn't matter.)

Answer 1

Answer:

40320 ways

Step-by-step explanation:

Required

Number of ways they can be selected

They can be selected in 8! ways

$8! = 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1$
