Tju [1.3M]

Answer:

C. 20

Step-by-step explanation:

The order in which the members are selected is important. The first one selected is the president and the second is the vice president.

So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this problem:

2 people are going to be chosen from a set of 5. So

P_{(5,2)} = \frac{5!}{(5-2)!} = 20

So the correct answer is:

C. 20

17+26 is different from 36+53 by if you add 17+26 the sum would be 43. And if you add 36+53 the sum would also be 89. So that means the way how they are  different is that the 17+26 and 36+53 has different kinds of sums. They have different kinds of sums because you are different numbers.
