    the person randomly selected has a 19 out of 100 chance of dying from cancer.

    the randomly selected nonsmoker has an 11 out 70 chance of dying from cancer.

    (btw smokers have a greater chance of dying because they are more prone to get lung cancer and throat cancer because they smoke.)
