Military Radar and missile detection systems are designed to warn a country of enemy attacks. A reliability question deals with the ability of the detection system to identify an attack and issue the warning. Assume that a particular detection system has a 0.85 probability of detecting a missile attack. Answer the following questions using the Binomial probability distribution.   A. If 3 systems are installed, what is the probability that at least 1 of the systems will detect the attack?   B. Would you recommend that multiple detection systems be operated? Explain.
