Step-by-step explanation:

The first place can be taken by any one of the 22 students.The second place can be taken by any one of the remaining 21 students.The third place can be taken by any one of the remaining 20 students.The fourth place can be taken by any one of the remaining 19 students.The fifth place can be taken by any one of the remaining 18 students.
