*) A infection originated from an unknown pollution can kill 40 percent of those who are already ill and make 60 percent of the healthy population ill each month. Assume that everyone is healthy initially and the death rate of the healthy population is negligible. a. Suppose that no one who is infected can become healthy again. Find the percentage of the original population that will die in the next four months. percent 5.184 b. It is found that a type of treatment can cure 10 percent of the infected population and reduce the death rate of the infected population to 30 percent each month. Find the percentage of the original population that will die in the next four months.
