What is the probability of randomly selecting one of the shortest diagonals from all the diagonals of a regular 7-sided polygon)?	Choose the correct option:
A) 1/2 B) 1/3 C) 1/4 D) 1/6 E) 1/7
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 2/4 = 1/2.   The answer is 1/2.
