Question

In a capture/recapture program, 30% of the animals recaptured have tags. Suppose 70 animals were originally captured, tagged and released. Estimate the population. Round to the nearest whole number.

Answer 1

Approximately , there are 233 animals in the forest.

Explanation:

There was a capture program of animals to get a count of the animals in that region.There were two rounds for that program. In the first round 70 animals were captured and all of them were tagged . In the second round , there were more animals caught but only 30% of those newly caught animals had tags.

Here we have to assume that no animal loses tag.

Let the total population be x .

Then 30% of the total population is 70.

Writing equation ,

`x * (30)/(100) = 70`

`x = \frac {70}{0.3}`

x =233 animals

Approximately , there are 233 animals in the forest.
