IV. Probability & Expected Value: Lecture 3 | 39:06 min

I have a question, in example 3 of geometpdf or geomcdf, you didn't include 0 person. But in examples of binomial, you included 0 person. So what's the difference? And should we include 0?

Hi,How do you get formula of variance of binomial distribution?Why Var(x)=np(1-p)?And for geometric distribution, I can't understand for both expected value and variance.Could you give me some explanation?Thanks a lot.
