In how many ways can a caravan of 8 covered wagons from arizona be arranged in a circle?

2520 ways.

Step-by-step explanation:

The formula for n wagons is (n - 1) ! / 2. We divide by 2 because all items are the same (like for example a necklace) and a clockwise arrangement is the same as a counterclockwise.

For 8 wagons the number of arrangements is (8 - 1) ! / 2

= 7! / 2

= 2520 ways.
