You can put this solution on YOUR website!
P(basketball) + P(softball) - P(basketball AND softball) = P(basketball OR softball)
\n" ); document.write( "
\n" ); document.write( "0.31 + 0.39 - P(basketball AND softball) = 0.50
\n" ); document.write( "
\n" ); document.write( "P(basketball AND softball) + 0.50 = 0.31 + 0.39
\n" ); document.write( "
\n" ); document.write( "P(basketball AND softball) + 0.50 = 0.70
\n" ); document.write( "
\n" ); document.write( "P(basketball AND softball) = 0.20
