i need d$,$e$,$f$,$g$,$h please solve.

Two random variables $x$ and $Y$ are distributed according to

$f_{x,Y}(x,y)=\{\begin{array}{ccc}K(x+y),& 0x,& y1\\ [0,& \text{o}\text{t}\text{h}\text{e}\text{r}\text{w}\text{i}\text{s}\text{e}& ].\end{array}$

d$)$ What is $P(x>Y|x+2Y>1)?$

e$)$ Find $P(x=Y).$

f$)$ What is $P(x>0\mathrm{.}5|x=Y)?$

g$)$ Find $f_x(x)$ and $f_Y(y).$

h$)$ Find $f_x(x|x+2Y>1)$ and $E(x|x+2Y>1).$
