There are 15 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 15 points that contain the point A?  Select
A) 91	B) 105	C) 182	D) 210	E) 455
Any 2 points out 14 points will create triangle with third point A, so the answer is C214=91.   91nswer: 91.
