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 Magnitude Light Debris 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 and B denote the events that the earthquake magnitude is low and the road debris is heavy respectively. Is the following statement True or False? Statement: “A and B are independent events”

While watching a game of Champions League football in a cafe, you observe someone who is clearly supporting Manchester United in the game. What is the probability that they were actually born within 25 miles of Manchester ? Assume that: The probability that a randomly selected person in a typical local bar environment is born within 25 miles of Manchester is 1/20 the chance that a person born within 25 miles of Manchester actually supports United is 7/10 the probability that a person not born within 25 miles of Manchester supports United with probability 1/10

An article in The Journal of Data Science [“A Statistical Analysis of Well Failures in Baltimore County” (2009, Vol. 7, pp. 111-127)] provided the following table of well failures for different geological formation groups in Baltimore County. Geological Formation Group Failed Wells Total Wells Gneiss 170 1685 Granite 2 28 Loch raven schist 443 3733 Mafic 14 363 Marble 29 309 Prettyboy schist 60 1403 Other schists 46 933 Serpentine 3 39 Let A denote the event that the geological formation has more than 1000 wells, and let B denote the event that a well failed. Determine the number of wells in each of the following events. Find the following,
