    I need some serious help on this problem attached.

    I can do all but a) and b) which is where I need help!

    So if someone could give me some help with this question a) and b) that would be great.

    Here is what I have so far:

    I know the marginals for X and Y

    f_X(x)=1 if x∈[0,1], 0 otherwise

    and

    f_Y(y)=1 if y∈[0,1], 0 otherwise

    but I don't know what to do now.

    Please help!

    ...
    a)

    If X,Y are independent, then:

    f_{X,Y}(x,y)= f_X(x)f_Y(y)

    And b)

    F(x,y) = \int_0^y\int_0^x f_{X,Y}(u,v) \; \text{dudv}

    in this case.

    Edit: And why am I on TSR a this time!
