A local school district studying the possibility of requiring that all children be vaccinated against childhood diseases and have an eye exam before they can be admitted to school. Presently, 80% of the children have had their vaccinations; 60% have had an eye exam; 45% have both. If a child is randomly selected, what is the probability that the child will: a) Not have had an eye exam? b) Will have been vaccinated or have an eye exam? c) Will not have been vaccinated but will have had an eye exam?

The blood-typing system is based on the presence or absence of antigens. A person with antigen A has blood type A. A person with antigen B has blood type B, and a person with both antigens has the blood type AB. If there are no antigens, then the blood type is O. In addition, blood types are also identified as Rh-positive or Rh-negative based on a different antigen. What is the probability that a person has the A antigen or is Rh-positive?
