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.

Now we are asking questions about the distribution of X given Y. As you stated, the conditional PDF of X given Y is. f ( X = x Y = y) = f ( X = x, Y = y) f ( Y = y) For the ease of understanding, we can define a new continuous variable Z y that is equal in …

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.
