Biologists tagged 177 fish in a lake on January 1. On February 1, they returned and collected a random sample of 26 fish, 13 of which had been previously tagged. On the basis of this experiment, approximately how many fish does the lake have?

354

Step-by-step explanation:

We have the following formula:

actual population / captured population = tagged population / tagged population captured.

We have the following data:

captured population = 177

tagged population = 26

tagged captured population = 13

Replacing:

real population / 177 = 26/13

solving:

real population = 177 * 2 = 354

In other words, there are a total of 354 fish.
