An аrticle in the Trаnspоrtаtiоn Research Part E Jоurnal ["Arc Routing Problems to Restore Connectivity of a Road Network" (2016)] considered ways of  re-establishing  the connectivity of road networks after a natural disaster — earthquake. Estimates of the probabilities of a randomly chosen road being under light debris, moderate debris, and heavy debris conditions after different disaster magnitudes are shown in the following table. Disaster magnitude is equally likely to be low, moderate or high. DisasterMagnitude   LightDebris ModerateDebris HeavyDebris Total Low   80 15 5 100 Moderate   50 40 10 100 High   30 50 20 100 Total   160 105 35 300 Let A" id="MathJax-Element-1-Frame" tabindex="0"> and  B" id="MathJax-Element-2-Frame" tabindex="0">  denote the events that the earthquake magnitude is  high and the road debris is  moderate.  Are these events independent?
