Refer to the Current Zoology (Apr. 2014) study of crop damage by wild boars, Exercise 3.18 (p. 129). Recall that researchers identified 157 incidents of crop damage in the study area caused by wild boars over a five-year period. The table giving the types of crops destroyed and corresponding percentage of incidents is reproduced below. The researchers also determined that of the cereal crops damaged, 71% involved wheat, barley, or oats. For one randomly selected incident, what is the likelihood that the wild boars damaged a wheat, barley, or oats cereal crop?
