So the bin has $\"65\"$ good, $\"12\"$ bad, $\"77\"$ total.
\n" ); document.write( "P(1st good)= $\"65%2F77\"$
\n" ); document.write( "P(2nd good)= $\"65%2F77\"$
\n" ); document.write( "P(3rd good)= $\"65%2F77\"$
\n" ); document.write( "P(4th good)= $\"65%2F77\"$
\n" ); document.write( "P(5th good)= $\"65%2F77\"$
\n" ); document.write( "P(all good)= $\"%2865%2F77%29%2865%2F77%29%2865%2F77%29%2865%2F77%29%2865%2F77%29\"$
\n" ); document.write( "P(all good)= $\"0.4287\"$

\n" ); document.write( " $\"P=0.844\"$ is the probability of picking the first good one out.
\n" ); document.write( "But you're doing it 5 times, so you need to multiply that value 5 times.
