Anthony has just received Covid-19 test results from a patient named Melania. The accuracy of thetest is as follows: the probability the test will be positive if Melania has Covid-19 is p, and theprobability the test will be positive if Melania does not have Covid-19 is q.

Consider the experiment: You ask someone two multiple-choice questions. Each question could be answered with Yes (Y), No (N), or Don't Know (D). (For example, if you ask someone these two questions, they could answer Yes to both of them, or Yes to the first one and Don't Know to the second one, etc.) Let A be the event that the person answers Yes to at least one question, and Let B be the event that the person answers No to the second question. How many elements are in the sample space? What elements are in A ∩ B? What elements are in A ′?

Chris has just received test results from a patient named Cardi who is infected with a mystery disease. The accuracy of the test is as follows:The probability the test will be positive if Cardi is infected is p, and the probability the test will be positive if Cardi is not infected is q. The proportion of the population that is infected is π. The test comes back positive. Chris has no information about the disease and related symptoms. Suppose Chris does not have a true gasp of the base rates. Chris thinks that the base rate is γπ (gamma*pi), with γ is less than or equal to π. This is to make sure that Chris's belief about the prevalance of the mystery disease is no more than 100%. If p=0.95, 1=0.05, π=1, what must be the value of γ if Chris thinks that the probability Cardi has the disease is 0.9? A. 3.57 B. 0.5 C. 1.05 D. 3.214 Please provide explanation
