The circle graph in the figure below shows the number of blood donors of each blood type who participated in the previous blood drive at a community college.

The letter in the blood type indicates the ABO group of the blood - this refers to the presence of the "anti-A" and/or "anti-B" immunoglobulin antibodies in the blood: type A blood has "anti-A" antibodies, type B blood has "anti-B" antibodies, type AB blood has both antibodies, and type O blood has neither.
