Q:

At a game show, there are 8 people (including you and your friend) in the front row. The host randomly chooses 3 people from the front row to be contestants. The order in which they are chosen does not matter. How many ways can you and your friend both be chosen?

Accepted Solution

A:
Answer:A. C(3,8) = 56Step-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.
