Question 13 A large scale study conducted over a one year period has shown that break-ins at home occur about 7% of the time in the population. The study also shows home security alarms went off 5% of the time when no one was breaking into the home. The security alarm ailed to go of 2% of the time when someone was really breaking into the home. If an alarm is going ott what isExplanation / Answer
Probability that break-in happens, P(B) = 0.05
Probability that security alarm went off when someone enters, P(A) = 0.97
Probability that a home has been broken into and the alarm went off is 0.05*0.97 = 0.0485
Option A is correct
