Explanation

The first person will sit down and the remaining will join i.e. (n-1)! = (5-1)! = 4! = 24waysTo find the number of ways five people can sit around a circular table, we can use the concept of circular permutations.The formula for circular permutations is (n-1)!, where n is the number of objects (in this case, people).In this case, n = 5 (number of people).Therefore, the number of ways five people can sit around a circular table is:(5-1)! = 4!Calculating 4! (4 factorial):4! = 4 * 3 * 2 * 1= 24Therefore, there are 24 ways five people can sit around a circular table.
