Hey guys, I need your help!

The whole permutation stuff is pretty new to me. My teacher taught the class this recently, but I am still unsure on what to do. I would love it if anyone out there who can provide a step-by-step instructions and an explanation please!

Step-by-step explanation:

Permutation is "How many ways can you arrange 'r' from a set of 'n' if the order matters?"

For #7, it would be "how many ways can you pick 2 things out of 6 things when the order matters?"

The steps for this is in the picture.

For #9, you would do the same as #7 and just add -4 to your final answer
