You can put this solution on YOUR website!
Here, P(A) = 300/1000, P(B) = 550/1000, and P(A & B) = 75/1000\r
\n" ); document.write( "\n" ); document.write( "==> P(A|B) = P(A&B)/P(B) = $\"%2875%2F1000%29%2F%28550%2F1000%29+=+3%2F22\"$ , and \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "==> P(B|A) = P(A&B)/P(A) = $\"%2875%2F1000%29%2F%28300%2F1000%29+=+1%2F4\"$ . \n" ); document.write( "

\n" );
