A) What is the probability that a randomly selected adult has a high BMI? B) What are the conditional probabilities that a randomly selected adult has a high BMI, given each country income level? Write up your findings in context. C) Compute and compare (high BMI ? high-income country) and (high-income country ? high BMI). Explain why they are not the same. Express each probability in a sentence in context.
