What's your Blood Type?
One of the main ways that blood is classified is using the ABO system. This system classifies blood based on whether it contains antigens of type A and type B. A person's blood can contain 0, 1, or both of these antigens. In Poland, \(46\%\) of people have the A antigen in their blood, \(25\%\) of people have the B antigen in their blood, and \(37\%\) of people have neither antigen. What percentage (in %) of people have both antigens?
