    ans will be 1/3 which is correct ... if p1 select 1st chair then p2 will select 2nd chair so probability= 1/6*1/5... now if p1 select any chair between 2 to 5 (probab=1/6)then p2 will have 2 choices either on the left or right(probab=2/5)...and probababilty for ist n last chair will be same so probability=1/6*1/5+1/6*2/5+1/6*2/5+1/6*2/5+1/6*2/5+1/6*1/5=1/3
