10 points lie in a plane, of which 4 points are collinear. Barring these 4 points no three of the 10 points are collinear. How many distinct quadrilaterals can be drawn?

There are 10 points in a plane of which 4 are collinear. No three of the remaining 6 points are collinear. How many different straightlines can be drawn by joining them?

There are 20 points in a plane, of which 5 points are collinear and no other combination of 3 points are collinear. How many different triangles can be formed by joining these points?

There are n points in a plane of which m points are collinear. How many lines can be formed from these points ?

There are 16 points in a plane of which 6 points are collinear and no other 3 points are collinear.Then the number of quadrilaterals that can be formed by joining these points is
