Answer:

Explanation:

We are told that of each 5 fish inspected in the tank, 4 have fin rot, therefore, the probability o getting a fin rot is

[tex]\frac{4}{5}\times100\%=80\%[/tex]

This means 80% of the fish in a tank have fin rot.

Now, for one tank 80% of 40 fish is

[tex]\frac{80\%}{100\%}\times40=32[/tex]

Now, since there are 5 fish tanks in the store and 32 fish in each have fin rot; therefore, the total number of fish that have fin rot will be

[tex]32fish\times5=160\text{fish}[/tex]

Hence, the estimated number of fish with fish rot in the store is 160.
