    Predicting the number of fish in a lake | 
  2018-09-16 | 
   
    | 
  From April: A researcher catches 30 fish in a pond, attaches a marker to their fin and releases them. The next day she places a large net in the water and catches 9 fish. 3 have the marker attached to their fin. Can she predict the number of fish in the pond???
