Answer:
there are 720 ways to arrange the 7 friends around the circular table at the wedding reception
Explanation:
The number of ways to arrange n distinct objects in a circle is (n-1)!, since there are n ways to choose the starting point, and then (n-1)! ways to arrange the remaining objects in a circle.
In this case, we have 7 friends seated around a circular table, so the number of ways to arrange them is:
(7-1)! = 6! = 720
Therefore, there are 720 ways to arrange the 7 friends around the circular table at the wedding reception.
