The graph shows that U.S. adults dependent on tobacco have a greater probability of suffering from some ailments than the general adult population. When making two or more selections from populations with large numbers, such as the U.S. adult population or the population dependent on tobacco, we assume that each selection is independent of every other selection. In Exercises 27-32, assume that the selections are independent events. an Independent and then a Democrat.
