Potpourri for 500

• Game wardens use experiments to help determine
  the number of fish in a lake. Suppose 120 fish
  are caught, tagged, and released back into the
  lake. Two weeks later 40 fish are caught, 4 of
  which are found to have tags. Using this
  information, estimate the number of fish in the
  lake.

1200 fish are in the lake. Set up a proportion
comparing tagged to total fish.
