    The thread is about probability - DID I JUST BLOW YOUR MIND




    please some one should help me solve this.
    Two four-sided die with numbers 1,4 on the faces are thrown. Let the two discrete random variables U and V, be the sum of the outcomes for the individual die and their product respectively.
    (i) What is the sample space for the possible outcomes?
    (ii) Derive the joint, probability mass function p(U, V).
    (iii) Find the marginal probability mass functions of U and V.
    (iv) Are U and V independent? Specify the reason.
    (v) Find E(U), E(V), Var(U), Var(V) and Cov(U, V).

    I don't have emotions and sometimes that makes me very sad.

    Shoot the answer is always (c) when you don't know but these dog gone Roman numerals.
