The table gives the percents of U.S. residents who participated in the recommended amount of physical activity, who participated in an insufficient amount of physical activity, and who were inactive, categorized by race or origin.

(a) What is the probability a Black person participated in the recommended amount of physical activity?

(b) What is the probability a White person did not have the recommended amount of physical activity?

(c) What is the sum of the probabilities in the "Hispanic" column? Does that mean that all categories of physical activity for Hispanics are included in the table?
