Answer:

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.
