here i still cant get the hang of it

Answer 12

ohhh oopsies :P

Answer 13

12!

Answer 14

there are 5 positions and the order of them matters, so it is a permutation. so you do
12*11*10*9*8
because each time you choose someone for a position, you have one less person in your student pool to choose from.

Answer 15

12P5

Answer 16

>.< im loooost

Answer 17

tonks taught me physics

Answer 18

My bad, didn't see how many different positions haha, just saw 12 members and saw "ways". yeah, Tonks is correct.

Answer 19

okay, you start with 12 students to choose from for President, so there are 12 possible outcomes, once you pick a president, there are only 11 students to choose from, so it goes until all the positions are filled:
12*11*10*9*8
We can talk about why you multiply if you need to
