The actual fraction of tagged trout is 125/p, using p = trout population of the lake.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The later sampling of 112, containing 62 tagged trout gives you a ratio which is very close-to the 125/p ratio.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"125%2Fp=62%2F112\"
\n" ); document.write( "\"p%2F125=112%2F62\"
\n" ); document.write( "\"p=125%2A112%2F62\"
\n" ); document.write( "\"p+=+225\" or \"p=226\" trout.
