Step 1
It is the sum of the joint probability distribution over all values of the other variables. (a) The marginal distribution of X is obtained by summing the joint distribution over all values of Y. Let's assume that the joint distribution is represented in a 2x3 Show more…

Consider the following joint probability density function of the random variables $X$ and $Y$ : $$ f(x, y)=\left\{\begin{array}{ll} \frac{3 x-y}{11}, & 1<x<3,0<y<1, \\ 0, & \text { elsewhere. } \end{array}\right. $$ (a) Find the marginal density functions of $X$ and $Y$. (b) Are $X$ and $Y$ independent? (c) Find $P(X>2)$
