Question
Find the covariance of the random variables $X$ and $Y$ having the joint probability density function.$${f}(x, y)=\left\{\begin{array}{l}+y \\0\end{array}\right.,$$$$0<x<1,0<y$$
Step 1
The expected value of a random variable is the long-term average or mean value of the random variable. It is calculated by multiplying each possible outcome by its probability and then summing all these values. The expected value of $X$, denoted $E[X]$, is given Show more…
