I have a random variable X, with distribution.

I take n samples of this r.v., all independent, with distribution , and I want to find the Fisher's information and hence the Cramer-Rao lower bound.

So, obviously, I have the pmf of the Bin dist:

So the first step would be to take the log of the pmf, correct?

If so, how do I do this? How do I take the log of ?
