Mike has 5 marbles, each of a different color; in how many ways can he arrange his marbles on a circle he drew on the floor?
To count CIRCULAR arrangements:
1. Place one element in the circle.
2. Count the number of ways to arrangement the REMAINING elements RELATIVE to the first element.
In the problem above, once the first marble has been placed, the number of ways to arrange the remaining 4 marbles relative to the first marble = 4! = 24.
