There are 13 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 13 points that contain the point A?	Choose the correct option:	A) 66	B) 105	C) 182	D) 210	E) 455
Any 2 points out 12 points will create triangle with third point A, so the answer is 12C2=66.   66nswer: 66.
