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 = [tex]\frac{n!}{r!(n-r)!}[/tex]
Plug in n = 6 and r =2, in the above formula, we get
= [tex]\frac{6!}{2!(6-2)!}[/tex]
= [tex]\frac{6!}{2!4!}[/tex]
Simplifying the above factorial, we get
= 15
So the answer is C) 15
