document.write( "If A and B are DEPENDENT, then there is not enough information,\r\n" );
document.write( "as you would need either P(A) or P(B).\r\n" );
document.write( "\r\n" );
document.write( "However if you mistyped, and \"DEPENDENT\" should have been\r\n" );
document.write( "\"INDEPENDENT\", then P(A|B) = P(A) = 0.15\r\n" );
document.write( "\r\n" );
document.write( "Then since P(B|A) = P(B∩A)/P(A) = P(A∩B)/P(A) = 0.15/0.15 = 1\r\n" );

document.write( "Then\r\n" );

document.write( "P(A∩B)/P(A) = 1, then multiplying both sides by P(A)\r\n" );
