<PRE><B>Question 1131618</B>

45.3% of the donors had the A antigen.
14.7% of the donors had the B antigen.
4.7% of the donors had the A antigen and the B antigen.
84.3% of the donors were Rh+.
87.5% of the donors had the B antigen or were Rh+.


a. P(have the A antigen or the B antigen) = {{{45.3+14.7 = 60}}}%
-------------------
b P(have the B antigen and are Rh+) = P(B+)+P(Rh+)-P(B+ or Rh+)
= {{{45.3+84.3-60 = 69.6}}}%</PRE>
