Use the [05] 5 letters A, B, C, D, E, and F to identify the items, and list each of the different combinations of three items. Q-2 Consider the experiment of tossing a coin three times. (a) Develop a tree diagram for the experiment. (b) List the experimental outcomes. What is the probability for each experimental outcome? 1/6 105) 5 2/3/6 Q-3 (c) Suppose that we have two events, A and B, with P(A)=0.50. P(B)=0.60, and [05] 5 2/3/6 P(AB)=0.40. Q-3 (a) Find P(A|B). (b) Find P(BIA). (c) Are A and B independent? Why or why not? OR The prior probabilities for events A, and A, are P(A)=0.40 and P(A2)= 0.60. It is also known that P(A, A₂) 0. Suppose that P(BIA) 0.20 and P(BIA)=0.05. (a) Are A1 and A2 mutually exclusive? Explain. (b) Compute P(A 1 n B) and P(A 2 n B). (c) Compute P(B). (d) Apply Bayes' theorem to compute P(A.1 | B) and P(A_2|B). Q-4 AA [05] 5 2/3/6 Military radar and missile detection systems are designed to warn a country of [10] 5 1/2/6 an enemy attack. A reliability question is whether a detection system will be able to identify an attack and issue a warning. Assume that a particular detection system has a 0.90 probability of detecting a missile attack. Use the binomial probability distribution to answer the following questions. (a) (b) (c) What is the probability that a single detection system will detect an attack? If two detection systems are installed in the same area and operate independently, what is the probability that at least one of the systems will detect the attack? If three systems are installed, what is the probability that at least one of the systems will detect the attack? Page 2 / 3 (d) Would you recommend the mumpre detection systems be used?
