So the mean of this distribution, which will actually be not a value that this distribution can take on, is going to be someplace over here. And it is going to be equal to P. Now, my country has 100 million people. It is practically or is definitely impossible for me to be able to go and ask all 100 million people who are they going to vote for. So I won't be able to exactly figure out what these parameters are going to be, what my mean is, what P is going to be. But instead of doing that, what I'm going to do is do a random survey. I'm going to sample this population, look at that data, and then get an estimate of what P really is. Because this is what I really care about.
