In how many ways can a team of 5 be selected from 8 people such that either all three specific persons from the eight are selected or none of them are selected.
1) 11 2) 9 3) 10 4) 8

• Ans :- 11
  
  Solution:-
  
  Total no of people = 8
  Select no of people = 5
  
  So that,
  all three specific person choose with other two = 5C2 =10
  without all three specific person choose with other five = 5C5 =1
  
  10+1=11 way a team can be selected
