Suppose $x$ and $Y$ are discrete, with

$f_{x,Y}(x,y)=\{\begin{array}{ccc}\frac{1}{5},& if(x,y)in\{(2,3),(3,2),(3,3),(2,2),(3,& 17)\},\\ 0,& \text{o}\text{t}\text{h}\text{e}\text{r}\text{w}\text{i}\text{s}\text{e}& \end{array}$

a$)$ Compute $|]=[3$ :

b$)$ Compute $|]=[3$ :

c$)$ Compute $[Y|]$ :

d$)$ Compute $[x|]$ :
