Question

Let X and Y be joint continuous random variables with joint probability density function $f(x, y) = \begin{cases} \frac{2}{3}(x + 2y) & 0 < x < 1, 0 < y < 1 \\ 0 & \text{else} \end{cases}$ Are X and Y independent? Round to 4 decimal places if needed.

Step 1

Step 1: To determine if X and Y are independent, we need to check if the joint probability density function can be factored into the product of the marginal probability density functions of X and Y. Show more…
