Consider the following joint probability density function of the random variable X and Y:
f(x,y) = (3x - y) / 9 for 1 < x < 3 and 1 < y < 2
a) Find the marginal distributions of X and Y.
b) Are X and Y independent?
C) Find P(X > 2)
Not sure how to do this. I missed the class that went over it. Can someone show me how to do this? Thanks
