So we can make n + n(n-4) = n^2 - 3n = n(n-3) triangles using either one or two edges, and our probability is: Hi Ian, can you please point out the flaw in my calculation for the numerator. Atleast 1 side of the polygon can be selected in n ways for n sided polygon...This gives you the 2 vertices o...

DS - Aboslute Values
source MGMAT CAT
Is there a quick way to solve this ?
If a and b are integers, and |a| > |b|, is a · |b| < a – b?
(1) a < 0
(2) ab is greater than or equal to 0
Has anyone come across any quick approach to this problem (not the one in the provided by MGMAT)
