P(A)+P(B)-P(A+B)=P(A or B)
\n" ); document.write( "P(E)=0.5
\n" ); document.write( "0.5+P(M)-P(E+M)=P(E or M)
\n" ); document.write( "P(E+M)=0.6
\n" ); document.write( "P(E or M)=0.8
\n" ); document.write( "so
\n" ); document.write( "0.5+P(M)-0.6=0.8
\n" ); document.write( "P(M)=0.9
\n" ); document.write( "
