Bayesian+Belief+Networks

You have a new burglar alarm at home that is quite reliable at detecting burglars but may also respond at times to an earthquake. You also have two neighbours, John and Mary, who promise to call you at work when they hear the alarm. John always calls when he hears the alarm but sometimes confuses the telephone ringing with the alarm and calls then. Also, Mary likes loud music and sometimes missed the alarm.

Who is more reliable when burglary happened? Mary or John? Proof by using Bayesian Network.
