Q4. In an effort to control the spread of the malaria virus, the World Health Organization (WHO) monitors the number of new cases each month in twelve countries in Africa, to initiate containment efforts if the number of new cases exceed 20 each month in any of the twelve countries. If a random variable is used to track the number of countries in which the number of new cases have exceeded 20 each month, how many values are possible for the random variable?
