The center of a circle is at the origin of a rectangular coordinate plane. If the points \((-3,0)\), \((0,3)\), and \((3,0)\) are on the circumference of the circle, what is the probability that a randomly selected point from within the circle will fall within the triangle formed by those three points?
(A)\(\frac{1}{4}\) (B)\(\frac{1}{\pi}\) (C)\(\frac{1}{3}\) (D)\(\frac{\pi}{4}\) (E)\(\frac{\pi}{3}\)
B
