Question

Scott works at an electronics store. He is setting up 6 different-sized TVs on a shelf. How many different ways can the TVs be set up?


A. 5!

B. 7!

C. 6!

D. 8!

Answer 1

You asked a similar question before. Imagine he just has 3 TVs
A B C
A C B
B A C
B C A
C A B
C B A

makes 3 * 2 * 1 = 3!

Answer 2

Well, one has to be the first put up. It can go into six different positions. The next one has only five places to be put. The next only four, etc. Since these are independent events (one decision does not depend on the previous), we multiply to get 6! possible combinations.

Answer 3

Thanks guys!(:
