choosing 2 people out of 10 in how many combinations can a particular person (some name) be always included….

• 9
  
  1 person should always be there
  remaining are 9
  so total possible combination is 9c1=9
  
  so total combination is 9*1=9

• 9
  
  because 1 is to be selected every time.so out of 10 people we remained with 9 choices.and now out of 9 only 1 person is to selected.
  therefore, 9C1=9.
