    What do you mean "likeliehood"? Is x a random variable? If so, what is its distribution?

    Re: minimum variance bound

    Ok using the cramer-Rao inequality find the minimum variance bound for unbiased estimators of lambda?

    The probability function is the poisson distribution, e^-lambda * lambda^x / x!

    Iv tried working it out and i get lambda/-n^2!!

    Cheers for helping me with this!!
