Tatiana [17]

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 = \frac{n!}{r!(n-r)!}

Plug in n = 6 and r =2, in the above formula, we get

= \frac{6!}{2!(6-2)!}

= \frac{6!}{2!4!}

Simplifying the above factorial, we get

= 15

So the answer is C) 15
