Well, I know what it's not..
Which of the following is an example of a combination?
A. Selecting a first, second and third place winner at a beauty competition.
B. Picking 4 sets of towels out of 20 different sets.
C. The number of ways 12 picture frames can be arranged on a shelf.
D. The number of ways 3 people can sit on a couch.
___
I know it cannot be option A because it is an example of a permutation. As for the others though, I have no idea.

Best ResponseYou've already chosen the best response.0actually, I think B would be the better answer usually, when you arrange something in a row (like picture frames or people on a couch), the order matters

Best ResponseYou've already chosen the best response.1B really wouldn't be good because picture frames and paintings have multiple combinations

Best ResponseYou've already chosen the best response.0About B, I wasn't sure if it was that one or not because it says 'different' sets.

Best ResponseYou've already chosen the best response.0for example, if we have three people, Ally Betty and Cathy sitting on a couch, then if Ally Betty and Cathy sit in the order ABC, it's different than the order BCA or ACB

Best ResponseYou've already chosen the best response.1B ONLY allows 4 SETS to be chosen out of 20

Best ResponseYou've already chosen the best response.0That fact I got down. I just forgot about the 'large' group part.

Best ResponseYou've already chosen the best response.0B is the better answer: if I pick 4 sets of towels, picking ABCD is the same as BCDA because it's the same 4 towels

Best ResponseYou've already chosen the best response.0well, maybe think about it this way: C and D are pretty much the same scenario with different numbers

Best ResponseYou've already chosen the best response.0I just don't know now because D is just a larger version of C. And A says 'different' sets.
