There are 12 points in a given plane, no three of which are on the same line. If one of the points is represented as 'A', then how many triangles can be determined with the 12 points that contain the point A?  Choose the correct choice from the following answers:
A) 55 B) 105 C) 182 D) 210 E) 455
Any 2 points out 11 points will create triangle with third point A, so the answer is 11C2=55.   55nswer: 55.
