Answer:
She can choose her electives in 20 ways.
Step-by-step explanation:
The order in which she chooses the courses is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
How many ways can she choose her electives?
3 electives from a set of 6. So
[tex]C_{6,3} = \frac{6!}{3!(6-3)!} = 20[/tex]
She can choose her electives in 20 ways.
