There are 15 points in a plane, no three of which are in a straight line except 4, all of which are in a straight line. The number of triangles that can be formed by using these 15 points is:

There are 15 points in a plane, no three of which are in a st. line, except 6, all of which are in a st. line. The number of st. lines, which can be drawn by joining them is :

Out of 18 points in a plane, no three are in the same straight line except 5 point which are collinear. Find the number of lines that can be formed by joining them?

There are 10 points in a plane, no three of which are in the same straight line, except 4 points, which are collinear. Find (i) the number of lines obtained from the pairs of these points, (ii) the number of triangles that can be formed with vertices as these points.

There are n points in a plane of which no three are in a straight line except 'm' which are all in a straight line. Then the number of different quadrilaterals, that can be formed with the given points as vertices, is
