This a \"capture-recapture\" problem. Scientists often use the \"capture-recapture\" method to determine the number of fish in lake or the number of deer in game preserve, for example.
\n" ); document.write( "Original number captured/Total number (x) = Total number tagged/Total number recaptured.
\n" ); document.write( " $\"302%2Fx+=+162%2F324\"$ Solve for x.
\n" ); document.write( " $\"302%28324%29+=+%28162%29%2Ax\"$ so...
\n" ); document.write( " $\"x+=+302%28324%29%2F162\"$
\n" ); document.write( " $\"x+=+604\"$
\n" ); document.write( "There are 604 deer in the game preserve. \n" ); document.write( "

\n" );
