SpletThe PDF gives us a helpful geometrical interpretation of the probability of an event: the probability that a continuous random variable X is less than some value b, is equal to the area under the PDF f ( x) on the interval (-∞, b ], as demonstrated in the following graph. Similarly, we have . What is Pr (X = x)? Splet1 Answer. Hint: 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. mkv 編集フリーソフト
