At a local bar in a small Midwestern town, beer and wine are the only two alcoholic options. The manager conducts a survey on the bar’s customers over the past weekend. Customers are asked to identify their sex (defined as male or female) and their drink choice (beer, wine, or soft drink). A portion of the responses is shown in the accompanying table.

a. Construct a contingency table that cross-classifies the data by Sex and Drink Choice. How many of the customers were male? How many of the customers drank wine? 

b. Given that a customer is male, what is the likelihood that he drank beer? Given that a customer is female, what is the likelihood that she drank beer? 

c. Construct a stacked column chart. Comment on the findings.
