All right, So we're talking about tech and CDs to a party. Doesn't say anything in this question about the order. You're gonna play the CDs in or order. You're gonna choose him. You're just taking five CDs. So in that case, Amanda is gonna be right that this is a combination because it doesn't matter the order. We're gonna take 30 CDs, and we're gonna choose five of them, so it is definitely a combination.
