Answer:
![Selection = 17100720\ ways](https://tex.z-dn.net/?f=Selection%20%3D%20%2017100720%5C%20ways)
Step-by-step explanation:
Given
![Students = 30](https://tex.z-dn.net/?f=Students%20%3D%2030)
i.e. first to fifth
Required
Determine number of selection
1st position = Any of the 30 students
2nd position = Any of the 29 students
3rd position = Any of the 28 students
4th position = Any of the 27 students
5th position = Any of the 26 students
Number of selection is then calculated as:
![Selection = 30 * 29 * 28 * 27 * 26](https://tex.z-dn.net/?f=Selection%20%3D%20%2030%20%2A%2029%20%2A%2028%20%2A%2027%20%2A%2026)
![Selection = 17100720\ ways](https://tex.z-dn.net/?f=Selection%20%3D%20%2017100720%5C%20ways)
