It is allowable to assume that the fish had time to evenly mix with the general population.
Since you caught 10% of the fish had tags (3/30), it makes sense that you caught 10% of the fish in the lake. If 40 is 10% of the population, the whole lake likely has around 400 fish.
check it. If there are 400 fish and 30 have tags, it makes sense that if you catch 40, 3 will have tags. ■
