The freshman class has 160 students. each freshman must write 3 reports from a list of 10 novels that the teacher has assigned them to read. how many different combinations of novels can a freshman student choose to write reports on? 30 120 480

Option B. 120

Step-by-step explanation:

The freshman class has students = 160

Total number of novels = 10

As, each freshman must write 3 reports , means selecting 3 novels out of 10 novels.

Here, order of choosing novels is not important.

So, we will apply rule of combinatorics here.

Selecting 3 novels out of 10 novels , is different combinations of novels that a freshman student  can choose to write reports on is given by

=

=

=

=

=

= 120

Option B 120 different combinations of novels can a freshman student choose to write reports.

i think this could be a possible answer (1 / 84) -1

good luck! : d
