Question: Deer and pine seedlings As suburban gardeners know, deer will eat almost anything green. In a study of pine seedlings at an environmental center in Ohio, researchers noted how deer damage varied with how much of the seedling was covered by thorny undergrowth:
(a) What is the probability that a randomly selected seedling was damaged by deer?
(b) What are the conditional probabilities that a randomly selected seedling was damaged, given each level of cover?
(c) Does knowing about the amount of thorny cover on a seedling change the probability of deer damage? Justify your answer.
