Given data;
Total no of students = 115
The total number of ways to elect a president = 115
If one person is elected as the president the total number of ways to elect a president = 114
The different ways that the students can elect a president and a vice president are found as;
⇒ 115 ways × 114 ways
⇒ 13110 ways
Hence the different ways that the students can elect a president and a vice president will be 13110.
