How many ways can the instructor choose the first group of four education students?
220
330
1,980
7,920

Answer 1

The answer is 330. Or answer B

Answer 2

The  instructor can  choose the first group of four education students in 330 ways.

What is combination?

Combination is used to obtain the number of ways in which an object can be selected.

Now we know that Mark is not part of the first group hence we have 11 students. Using the combination formula; 11!/4!(11-4)! = 330

Therefore, the  instructor can  choose the first group of four education students in 330 ways.
