You can put this solution on YOUR website!
\" the two events are independent\", so \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(A and B) = P(A)*P(B)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(A and B) = 0.20*0.50\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(A and B) = 0.10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now use this to find the probability of P(A or B)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(A or B) = P(A) + P(B) - P(A and B)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(A or B) = 0.20 + 0.50 - 0.10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(A or B) = 0.70 - 0.10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "P(A or B) = 0.60 \n" ); document.write( "

\n" );
