Joint density of (X, Y) is given by f(x,y) = \begin{cases} x+y & 0<x<1 \\ 0 & \text{elsewhere} \end{cases} 0<y<1 a-) Find the density of Z = XY b) Find Cov(X,Y)

The joint density function of X and Y is given by: Find E[X], E[Y], and show that Cov(X,Y) = 1.

The joint density of $X$ and $Y$ is given by $$ f(x, y)=\frac{e^{-y}}{y}, \quad 0<x<y, \quad 0<y<\infty $$ Compute $E\left[X^{3} | Y=y\right]$

Explaining Density In your own words, explain what the concept of density means—without using the formula. Density is a measure of how much mass is contained within a given volume of a substance. It describes how tightly packed the particles or molecules of a substance are. A substance with a higher density has more mass in a given volume compared to a substance with a lower density. Density can be thought of as a measure of compactness or heaviness of a substance. It is an important property in various fields such as physics, chemistry, and engineering.
