Question

I need some help

Answer 1

Here

Answer 2

Since order matters, use permutations. You will need to do two seperate things since it is a group of 3 and then a group of 5, and multiply them together

\(\Large \frac{8!}{(8-3)!}\times\frac{8!}{(8-5)!}\)

Answer 3

Wait, I think I did that wrong...

Answer 4

Oh, sorry I didn't fully read the question. You only want to do the people in the three chairs, so just do \(\Large\frac{8!}{(8-3)!}\)

Answer 5

1.6 x 2.6

Answer 6

Remember that 8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Answer 7

Oh so C will be my Official Answer

Answer 8

No, not C. REmeber the (8-5)! part

Answer 9

How do you remember things like this

Answer 10

\(\Large\frac{8!}{(8-3)!}\rightarrow \frac{8*7*6*5*4*3*2*1}{5!}\rightarrow \frac{8*7*6*5*4*3*2*1}{5*4*3*2*1}\)
