Answer:
c. 60.278%
Step-by-step explanation:
There is a 27.778% probability that someone owns a dog.
There is a 45% probability that someone is a male.
However, these two are not mutually exclusive. 12.5% both own a dog and are male. If we simply add 27.778% and 45%, we'll be double counting the overlap. To avoid this, we subtract 12.5%.
27.778% + 45% − 12.5% = 60.278%
