Discussion:
According to Link Resources, 16% of the U.S. population is technology driven. However, these figures vary by region. For example, in the West the figure is 20% and in the Northeast the figure is 17%. Twenty-one percent of the U.S. population in general is in the West and 20% of the U.S. population is in the Northeast. Suppose an American is chosen randomly.
a. What is the probability that the person lives in the West and is a technology-driven person?
b. What is the probability that the person lives in the Northeast and is a technology-driven person?
c. Suppose the chosen person is known to be technology driven. What is the probability that the person lives in the West?
d. Suppose the chosen person is known not to be technology-driven. What is the probability that the person lives in the Northeast?
e. Suppose the chosen person is known to be technology driven. What is the probability that the person lives in neither the West nor the Northeast?
