There are 11 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 11 points that contain the point A?  Pick one.
A) 45	B) 105	C) 182	D) 210	E) 455
Any 2 points out 10 points will create triangle with third point A, so the answer is 10C2=45.   45nswer: 45.
