    Conditional distribution based on a trivariate density function
    Help please. I have the basic idea about how to work with single variable but this one just blew me over.
    Derive a moment generating function, then find the mean and variance of

    f(x,y,z)= 4/9 xyz^2 0 less than or equal to x less than or equal to 1,
    0 less than or equal to y less than or equal to 1,
    0 less than or equal to z less than or equal to 3


    NB. For the function it is zero elsewhere & z is actually raised to the second power.
