Answer:

A. C(3,8) = 56

Step-by-step explanation:

Since the order doesn't matter, it's a combination, not a permutation (answer C).

To calculate the possible combinations, we use the following formula:

[tex]C(n,r) = \frac{n!}{r! (n-r)!}[/tex]

In this case we have n = 8 (entire population), and r = 3 (number of chosen people)

[tex]C(8,3) = \frac{8!}{3! (8 - 3)!} = 56[/tex]

And you have 56 in your possible answers... so answer A.
