3. The following table gives the proportion of survey responses for customers from the Komcast cable/internet company. The row variable is the region of the country that the customer was in and the column variable is the customer satisfaction rating with Customer Service. Suppose that the table is representative of all Komcast customers and that a randomly selected customer is selected. a. Find the probability that the customer is from the Midwest and gave a Fair rating. b. Find the probability that the customer is from the Midwest or gave a Good rating. c. Find the probability that the customer is from the Midwest given a Good rating. d. Find the probability that the customer gave a Good rating given from the Midwest. e. Find the probability that the customer gave a rating other than Poor. f. Find the probability that the customer gave a rating other than Poor given the customer is from the North. g. Find the probability that the customer is from the North given a rating other than Poor. h. If a customer gave a rating of poor, which region was the customer most likely from. JUSTIFY!
