Explain how to get the vertical values when $n = 10$, $p = .5$, $\mu = 5$ and $\sigma^2 = 2.5$ 

I'm going through some PowerPoint slides in my class and they say that you can predict the shape of a binomial probability distribution just knowing $n$ and $p$ because $\mu = n * p$ and $\sigma^2 = n * p * q$.

The only things I understand are that the values should pile up at the mean and the horizontal axis should go up to 10. I have no idea how to predict the values on the vertical axis or how $\sigma^2$ comes into play.
