Question:
Ten points are marked on a straight line and eleven points are marked on another straight line. How many triangles can be constructed with vertices from among the above points?
Ten points are marked on a straight line and eleven points are marked on another straight line. How many triangles can be constructed with vertices from among the above points?
Show Hint
When calculating the number of triangles, remember that a valid triangle must not have all its vertices collinear. Check for any constraints before applying the combination formula.

The Correct Option is B
Solution and Explanation
The number of triangles that can be formed from 10 points on one line and 11 points on the other can be calculated using combination formula. Since all the points are collinear, the number of ways to select 3 points to form a triangle is computed.
