You can put this solution on YOUR website!
let's look at 1000 bikes\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "700 came from A, with 28 defective\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "300 came from B, with 33 defective\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a) 61 defective out of 1000 gives a .061 probability\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "b) 28 out of 61 defective are from A, so the probability is 28/61 or 0.459 (approx)
\n" ); document.write( "
\n" );
