NettetThe joint probability density function (joint pdf) of X and Y is a function f(x;y) giving the probability density at (x;y). That is, the probability that (X;Y) is in a small rectangle of … NettetThis is the normalization condition for joint probability density functions. Intuitively, the joint probability density function just gives the probability of finding a certain point in two-dimensional space, whereas the usual probability density function gives the probability of finding a certain point in one-dimensional space.

NettetThe joint density function of two continuos random variables X and Y is given by: f ( x, y) = 8 x y if 0 ≤ y ≤ x ≤ 1 and 0 otherwise. Calculate P ( X ≤ 1 2) Calculate P ( Y ≤ 1 4 ∣ X = 1 2) Calculate the expected value of Y 3 if X = 1 2. I would just like to check whether I am solving these questions in the right way. Nettet1 Answer. Sorted by: 5. First, you can see that X and Y are independent. This is because the joint pdf is: f X Y ( x, y) = e − ( x + y) = e − x e − y (read this for independent random variables if you are not sure). Also, you can get pdf of X, Y by integration of the joint pdf. f ( x) = ∫ 0 ∞ e − ( x + y) d y = e − x f ( y) = ∫ ...
