Answer 1

Hi Oswald.

 

We need to pick a team of 3 people out of 8 available.

 

₈C₃ is the combination needed

 

     8!             8!          8*7*6*5*4*3*2*1        8*7*6

---------  = -------  =  -----------------------  = ---------- = 56

3!(8-3)!      3! 5!         3*2*1*5*4*3*2*1         3*2*1

 

There are 56 ways to pick 3 people out of 8.
