A₁, A₂, A₃,....An be the n-vertices of a regular polygon of n-sides inscribed in a circle with centre O. Triangles are formed by joining the vertices of this regular polygon. From these triangles, if a triangle is choosen at random

	COLUMN - I		COLUMN - II
A)	If n = 45 probability that the chosen triangle is equilateral	p)	0
B)	If n = 45 probability that the chosen triangle is right angled triangle	q)	$\frac{1}{946}$
C)	If n = 27 probability that the chosen triangle is acute angled triangle	r)	$\frac{1}{351}$
D)	If n = 27 probability that the chosen triangle is right angled triangle	s)	$\frac{7}{25}$
