\n" ); document.write( "Males 96 1013 1109
\n" ); document.write( "Females 700 1724 2424
\n" ); document.write( "Total 796 2737 3533
\n" ); document.write( "Male or a nursing major is 1109+796-both (96)=1809/0.512
\n" ); document.write( "Female or not a nursing major is 2424+2737-1724 (double counting)=3437/3533 (only male nursing majors are omitted. 0.973
\n" ); document.write( "Not a female or a nursing major leaves male non-nursing majors only, which is 1013/3533=0.287
\n" ); document.write( "Male and being a nursing major are not exclusive, because one can be a male and a nursing major. So the answer is C, No, they aren't mutually exclusive, because there are 96 males majoring in nursing.
