It depends on your population size, and if your sample is biased. If your sample was 40 out of 100, then yes, it would be reasonable. But if your sample was 40 out of 1000, then no because the sample is too small.

The student body of 115 students want to elect a president and a vice president. How many different ways can they do that
Hitman42 [59]

The different ways that the students can elect a president and a vice president will be 13110.

<h3>What is probability?</h3>

The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,

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.
