    Help with Poisson and other type questions

    Ive been trying to wrap my head around these questions for a few days now and i seem to be getting nowhere with it

    If anyone would take the time to help it would be greatly appreciated.

    Ive attached the pdf here because i thought it would be easiest.

    P.S. On another note does anyone know where i can find step by step derivations of mean and variance of negative binomial and Poisson random variables?

    Thanks again

    Poisson: http://www.mathhelpforum.com/math-he...tributiom.html

    Negative binomial: http://www.mathhelpforum.com/math-he...need-help.html contains what you need to do the calculations.

    This looks like an assignment that will contribute towards your final grade. MHF does not knowingly give help in such circumstances.
