Explanation

To calculate the number of ways seven people can sit around a table, you can use the formula for permutations of n objects taken r at a time in a circular arrangement:

P(n,r) = (n−1)!

Where n is the number of objects (people) and r is the number of positions to fill (seats).

So, for seven people sitting around a table, there would be 

(7−1)! = 6! ways.

6! = 6 × 5 × 4 × 3 × 2 × 1 = 720
