Using the data in Table 6,

(a) Determine the probability that a randomly selected U.S. resident 15 years old or older is male.

(b) Determine the probability that a randomly selected U.S. resident 15 years old or older is widowed.

(c) Determine the probability that a randomly selected U.S. resident 15 years old or older is widowed or divorced.

(d) Determine the probability that a randomly selected U.S. resident 15 years old or older is male or widowed.

Approach Add the entries in each row and column to get the total number of people in each category. Then determine the probabilities using either the Addition Rule for Disjoint Events or the General Addition Rule.
