In a wildlife preserve, 45 ducks are captured, tagged, and released. Later, 200 ducks are examined, and two of them are tagged. Estimate how many ducks are in the preserve.

There are 243 ducks in the preserve.

Explanation:

Given:

In a wildlife preserve, 45 ducks are captured, tagged, and released.

Later, 200 ducks are examined, and two of them are tagged.

To Find:

To estimate how many ducks are in the preserve = ?

Solution:

Now, we know that, out of 200 2 ducks are tagged, which means remaining 198 ducks are untagged.

Now, total ducks count = ducks with tags + ducks with out tag

Total ducks count = 45 + 198

Total ducks count = 243

Hence, there are 243 ducks in total.
