Eighty-three percent of the Canadian population now live in urban areas.2 Assume that about 15% of all Canadian adults care for ill relatives and that 11% of adults living in urban areas care for ill relatives.
a. Use the general law of multiplication to determine the probability of randomly selecting an adult from the Canadian population who lives in an urban area and is caring for an ill relative.
b. What is the probability of randomly selecting an adult from the Canadian population who lives in an urban area and does not care for an ill relative?
c. Construct a probability matrix and show where the answers to this problem lie in the matrix.
d. From the probability matrix, determine the probability that an adult lives in a nonurban area and cares for an ill relative.
