Given a collection of points P in the plane a 1-set is a point in P that can be separated from the rest by a line; i.e the pint lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P) . The maximum value of n1(P) over all configurations P of 4 points in the plane is  Answers:  A) 1  B) 2  C) 3  D) 4  E) 5
maximum no of 1-sets will be the no of points itself...as in even a simple configuration we can separate one point from others to make it 1-set   1NSWER:1
