5.19) According to data from the U.S. Energy information Administration, the 60.0 million U.S. households with personal computers were distributed as shown here with regard to geographic location and access to the Internet. The entries represent millions of households. What is the probability that a randomly selected computer household would be in the category described by (South or Midwest or Yes)? In the category (West and No)?
Access Region
To Internet? Northeast Midwest South West Total
Yes 9.7 11.8 16.9 12.2 50.6
No 1.2 2.3 3.8 2.1 9.6
Total 10.9 14.1 20.7 14.3 60.0

    We don ot have the data that is "shown here."

    However, for "West and No," find that cell and divide by the grand total.

    For the "South or Midwest or Yes," find each of those totals and divide each by the grand total. For "either-or" probabilities, you have to add these individual probabilities.

    I hope this helps. Thanks for asking.
