Question $7$

$1$ pts

I$\text{'}$m working in a store and putting up two different Halloween displays and three displays for specific merchandise. I want to vary which displays go where. I calculate the permutations for different possible orders among five displays. I get the number $600.$ Are there really $600$ different ways to arrange these five displays?

$$

Yes, because you care about order $--$ which one is in the front of the store, which one in the back, and so on $--$ permutations is the correct formula to use.

Yes, but this assumes you can repeat particular displays in many parts of the store.

No$,$ you should have used the formula for combinations.

No$,$ you should have figured out the number of combinations and divided that by the number of permutations.
