What is the probability of randomly selecting one of the shortest diagonals from all the diagonals of a regular 11-sided polygon)?
Select the correct option:
A) 1/2  B) 1/3  C) 1/4  D) 1/8  E) 1/11
From any vertex, there are two vertices on sides, which do not make a diagonal but a side.   So the remaining n-3 vertices make diagonals.   There are 2 of these diagonals which are the shortest.   The probability of choosing one of the shortest diagonals is 2/8 = 1/4.   The answer is 1/4.
