a. Draw a tree diagram that represents the experiment above and show the probability in each of the branches and the probability of the final outcomes.

b. If a person is selected at random in this region, find the probability that he or she will not contract the disease. (answer in 3 decimals)

c. If a person who contracted the disease is selected at random in the region, what is the probability that he/she was not vaccinated? (answer in 3 decimals)
