Consider the parabola `y^2=4x` . From a point A(1,0) tangents AB and AC are drawn. Normals at B and C intersect at D. A point is randomly chosen inside the quadrilateral ABCD. Let P denotes the probability when the point lies inside the parabola as well as inside quadrilateral. Then P is greater than- 0.2 (b) 0. 4 (c) 0.7 (d) 0.9
