A regional forestry division wanted to estimate the number of deer in a particular national park. They caught and tagged 56 deer and released them back into the park. Later they selected a sample of 540 deer. Of the 540 deer, 30 were tagged. Assuming that the proportion of tagged deer in the sample holds for all deer in the forest, what is the best estimate of the number of deer in the park?

If its asking for a sum of all deer, tagged and untagged, it would be 566.
540-30 = 510 remove tagged deer since you already know the amount tagged.
510 untagged. add tagged and untagged.
510+56=566
