document.write( "\r\n" );
document.write( "Since A and B are independent,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    P(A and B) = P(A)*P(B),\r\n" );

document.write( "\r\n" );
document.write( "    0.3 = 0.75*P(B).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It gives  P(B) = 0.3/0.75 = 0.4.    ANSWER\r\n" );
