A study of a double intrusion detection system with two independent monitoring systems was conducted. If there is an​ intruder, system A sounds an alarm with probability 0.85 and system B sounds an alarm with probability 0.95. If there is no​ intruder, system A sounds an alarm with probability 0.10 and system B sounds an alarm with probability 0.05. ​Now, assume that the probability of an intruder is 0.4. If both systems sound an​ alarm, what is the probability that there is an​ intruder?
