There are 14 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 14 points that contain the point A?
Pick one:  A) 78  B) 105  C) 182  D) 210  E) 455
Any 2 points out 13 points will create triangle with third point A, so the answer is 13C2=78.   78nswer: 78.
