12 points lie on a circle. How many cyclic quadrilaterals can be drawn by using these points?  Choose the correct choice from the following choices.
A) 334	B) 377	C) 495	D) 766	E) 261

Rationale: explanation : for any set of 4 points we get a cyclic quadrilateral . number of ways of choosing 4 points out of 12 points is \ inline { \ color { black } 12 c _ 4 { } } = 495 . therefore , we can draw 495 quadrilaterals answer : c ) 495
Answer: C
