Paragraph for Questions 3 and 4 Let S be the set of points {(x,y):0 <= x <= 3,0 <= y <= 4 where x,y in I} two distinct points are randomly chosen from S. 3. The probability that mid point of the line segment of two points chosen belongs to S is (A) (21)/(95) (B) (42)/(95) (C) (36)/(95) (D) None of these 4. If two points (x_(1),y_(1)) and (x_(2),y_(2)) are chosen such that x_(1)=x_(2) and y_(1)!=y_(2) then probability that mid point of these two points belongs to S, is (A) (1)/(5) (B) (2)/(5) (C) (8)/(15) (D) (8)/(95)
