    Covariance



    I tried using the formula:
    cov[V,W] = E[VW] - E[V]E[W]

    I assumed this takes on a binomial distribution with
    E[X] = np
    Hence for E[V] and E[W] I obtained 0.55n and 0.45n respectively. After this I am stuck on this question.

    Any hints would be greatly appreciated!
