## Mark recapture

The mark recapture method involves capturing, marking, and then releasing a portion of individuals in a population. After a sufficient amount of time for the marked individuals to reintegrate back into the population has passed, another portion of the individuals from the population are captured. From the number of marked individuals that are recaptured the total population size can be estimated (e.g. if 10 individuals were tagged and released, and then 10 individuals are recaptured, 2 of which were tagged, the population can be estimated to be 50 individuals). Create a model/equation that describes how the mark recapture method works. From your equation/model, compute the probability of finding a certain number of marked individuals.
