17!/13! is an annoying way to write "start with 17 and multiply descending values until you get to 14"...

...17!/13! = 17*16*15*14 then you divide by 4! 4! = 4*3*2*1

A student club has 12 members. How many ways can the club choose a President, Vice President, Secretary, and Treasurer? A. 12,300 B. 6,940 C. 11,880 D. 9,940\ here i still cant get the hang of it

12!

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.

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