Some information about the causes and symptoms of Heart Disease are available. The factors that affect a patient's chances of having heart disease are: * Diet (measured as Healthy or Unhealthy) Exercise (measured as Regular or Irregular) It is also known that if a patient has Heart Disease (measured as True or False) it will affect the patient's symptoms, namely: The patient having Chest Pain (measured as Severe or Mild) The patient experiencing Shortness of Breath (measured as Present or Absent) The following evidence is available about patients in general: 75% of patients maintain a Healthy Diet 50% of patients engage in Regular Exercise Of patients that have Heart Disease the following is known: * 10% have an Unhealthy Diet and Irregular Exercise * 15% have an Unhealthy Diet but engage in Regular Exercise * 5% have a Healthy Diet and Irregular Exercise 1 out of every 200 have a Healthy Diet and engage in Regular Exercise The following is known about the Chest Pain results of patients tested for Heart Disease: 18 out of 20 patients with Heart Disease experience Severe Chest Pain * 1 out of 10 patients who do not have Heart Disease experience Severe Chest Pain The following is known about the symptoms of Shortness of Breath: * 80% of patients with Heart Disease have symptoms of Shortness of Breath * 30% of patients who do not have Heart Disease have symptoms of Shortness of Breath Answer the following questions: a) Construct a Bayesian Belief Network that illustrates the conditional dependencies between the five variables, and draw a diagram to illustrate the network. b) On your belief network diagram, show the conditional probability tables for each of the five variables.
