In a plane, there are 37 straight lines, out of which 13 pass through the point A and 11 pass through the point B. Besides, no three lines pass through the same point, no line passes through both points A and B, and no two lines are parallel. The number of intersection points the lines have is equal to
Here my doubt is it is given that 13 pass through point A and 11 pass through point B. at the same time it is give that no three lines pass through the same point. how is this possible?
