Question: The U.S. Coast Guard maintains a database of the number, source, and location of oil spills in U.S. navigable and territorial waters. The following is a probability distribution for location of oil spill events:

Location Probability

Atlantic Ocean 0.011

Pacific Ocean 0.064

Gulf of Mexico 0.229

Great Lakes 0.014

Other lakes 0.005

Rivers and canals 0.223

Bays and sounds 0.151

Harbors 0.118

Other 0.185

Apply the special addition rule to find the percentage of oil spills in U.S. navigable and territorial waters that:

(b) occur in a lake or harbor.

(c) do not occur in a lake, ocean, river, or canal.
