WebHint: you should apply the rules of conditional expectation and variance: E ( Y) = E ( E ( Y X)) and var ( Y) = var ( E ( Y X)) + E ( var ( Y X)). The conditional distribution of X is a pretty easy one. The marginal distribution of Y is as well, but you must state what they are.

WebConditional probability is the probability of one thing being true given that another thing is true, and is the key concept in Bayes' theorem. This is distinct from joint probability, which is the probability that both things are true without knowing that one of them must be true. For example, one joint probability is "the probability that your left and right …

WebDeﬁnition 2. Let X,Y be jointly continuous random variables with joint density fX,Y (x,y) and marginal densities fX(x), fY (y). We say they are independent if fX,Y (x,y) = fX(x)fY (y) If we know the joint density of X and Y, then we can use the deﬁnition to see if they are independent. But the deﬁnition is often used in a diﬀerent way. fancy gap vacation rental blackberryWebI need to find a pdf of Y.
