### Can anyone help me regarding the solution?

Ecologists marked 60 fish in a little lake. A few days later a man caught 80 fish, of which five were marked. Estimate the number of fish in the lake.

Hi;

You need to estimate the MLE. Use this formula to do so:

n = 960 so that is the population of the fish in the lake using the most likely probability or MLE( maximum likelihood estimator)

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
