Hello, I am having trouble with this homework question
The population of a particular country consists of three ethnic groups. Each individual belongs to one of the four major blood groups. The accompanying joint probability table gives the proportions of individuals in the various ethnic group blood group combinations, Blood Group A 0.116 1 o 0.082 0.127 0.215 AB 0.004 0.001 0.020 Ethnic Group 2 0.01 0.018 0.075 0.141 0.190 3 Suppose that an individual is randomly selected from the population, and define events by A- (type A selected}, 8 - (type B selected}, and C - (ethnic group 3 selected). (a) Calculate PYA), PC), and PANC). (Enter your answers to three decimal places.) PIA) - PC) - PAC) b) Calculate both PAC) and PCJA). (Round your answers to three decimal places.) PAC) = PCJA) - Explain in context what each of these probabilities represents. (Select all thet apply.) If a person has type B blood, the probability that he is from ethnic group 3 is given by PCA). If a person has type A blood, the probability that he is from ethnic group 3 is given by PC|A). If we know that the individual came from ethnic group 3, the probability that he has type A blood is given by PAC). If we know that the individual came from ethnic group 3, the probability that he has type A blood is given by ACIA). Ir a person hes type A blood, the probability thet he is from ethnic group 3 is given by PAC). If a person has type B bload, the probability that he is from ethnic group 3 is given by PAI). (c) Ir the selected individual does not have type B blood, what is the probability that he or she is from ethnic group 1? (Round your answer to three decimal places.)
