Answer:

0.8333%

Explanation:

Assuming that there is only one possible shortest route, the probability that a randomly selected route is given by one divided by the permutation of the order of five different sites:


P=(1)/((5!)/((5-5)!))=(1)/(5*4*3*2*1)\\ P=0.008333=0.8333\%

There is a 1 in 120 chance, or 0.8333% chance that a randomly selected route is the shortest possible route.
