Answer by Edwin McCravy(20055) (Show Source): You can put this solution on YOUR website!



 

The number of 5-person committees that include Zubeda,
we choose Zubeda in exactly 1C1 = 1 way, and we choose the
other 4 members from the other 8 people in 8C4 ways.
That's 1 times 8C4 or 8C4.

The number of 5-person committees (whether or not they 
include or exclude Zubeda) is 9C5
