In Problem use the Venn diagram to indicate which of the eight blood types are included in each set.

A ∪ B

When receiving a blood transfusion, a recipient must have all the antigens of the donor. A person may have one or more of the three antigens A, B, and Rh or none at all. Eight blood types are possible, as indicated in the following Venn diagram, where U is the set of all people under consideration:
An A- person has A antigens but no B or Rh antigens, an O+ person has Rh but neither A nor B, an AB- person has A and B but no Rh, and so on.
