A researcher captures 50 penguins, marks them with a spot of paint on their bills, and releases them. One month later, the researcher returns, captures another 50 penguins, and notes that only 1 has a previous mark. What is the likely size of the total penguin population in the researcher’s study area?

You visit the Apalachicola National Forest and capture, mark and release 30 fence lizards. A week later you return and capture 25 lizards, 5 of which are recaptures from the previous sample. What is your best estimate of the lizard population size?
In an effort to measure the size of a bluegill population in a pond, you set 10 traps for bluegills. You catch and mark 40 with a tag on the tail fin and then release them. A week later you return to the pond and set 10 traps and you catch 40 more, of which 8 have a tag on the tail fin. What is the best estimate of the bluegill population in the pond?
