(b) 5400
(c) 5040
(d) 5004​

Answer 1

Answer:

So this was a worksheet on Permutations and Combinations that you can find online, which fortunately also provides the answers. However, I am concerned because the answer provided in class is different from the online key. Here is the question:

In how many ways may 8 people form a circle for a folk dance?

For this question, can't you just factorial 8, which would be 40320 ? The student assistant in my class says that the order of the circle does not matter.

However, on the online key, the answer is ((8!)/(8))= 7! = 5040.
