Number of persons = 5
Arranging them in a line involves different permutations, by altering their relative positions with respect to each other.
So the number of ways = 5P5 = 5! = 120
====
The number of ways of arranging them in a circular line:
When they are standing in a circle, the arrangement in clockwise and anticlockwise do not make difference. So the total number of different ways is half of the number of ways of arranging them in a line.
so answer for circular line: 5P5 ÷ 2 = 5! /2 = 60.
