Answer:
C) 15
Step-by-step explanation:
Here we have to use the combination to find the number of possible combinations.
Total number of classmates (n) = 6
We are selecting 2 individuals. So r = 2.
The combination formula nCr =
Plug in n = 6 and r =2, in the above formula, we get
=
=
Simplifying the above factorial, we get
= 15
So the answer is C) 15
