* Your answer is incorrect. An article in the Transportation Research Part E Journal ["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. Disaster Light Moderate Heavy Total Magnitude Debris Debris Debris Low 80 15 5 100 Moderate 50 40 10 High 30 50 20 00 Total 160 105 35 30 Let A and B denote the events that the earthquake magnitude is low and the road debris is heavy. Are these events independent? Yes, because P(A) # P(B) Yes, because road debris can be not only heavy after earthquake with low magnitude. No, because P(An B) > P(A) P(B) No, because P(An B) # P(A) P(B) No, because P(An B) = P(A) P(B) Yes, because P(An B) + P(A) P(B) Yes, because P(An B) = P(A) P(B)
