The level of crop damage by wild boars in southern Italy was investigated in Current Zoology (Apr. 2014). In the study, crop damage occurred when the wild boars partially or completely destroyed agricultural crops in privately owned lands. The researchers identified 157 incident of crop damage in the study area caused by wild boars over a five-year period. The accompanying table gives the types of crops destroyed and corresponding percentage of incident. Consider the type of crop damaged by wild boars for one randomly selected incident.
Type ______________ Percentage
Cereals ......................... 45%
Orchards .......................... 5
Legumes ......................... 20
Vineyards ...................... 15
Other crops ...................... 15
TOTAL ..................... 100%
a. List the possible outcomes of this experiment.

c. What is the probability that cereals or orchards are damaged?
d. What is the probability that a vineyard is not damaged?
