A marine biologist tags 100 whales. Later, a sample of 115 whales was gathered and 5 were tagged. Estimate the total whale population.

This is a hypergeometric distribution problem.
Assuming that the tagged whales are subsequently randomly distributed in the whale population, we have population N, where
N = (115/5)*100 = 2300 approximately.
For more accurate estimations, use the hypergeomatric distribution and maximize P(5).
