- Marginal distribution of X: P(X=1) = 0.28 + 0.245 + 0.175 = 0.7 P(X=2) = 0.12 + 0.105 = 0.225 P(X=3) = 0.075 - Marginal distribution of Y: P(Y=1) = 0.28 + 0.12 = 0.4 P(Y=2) = 0.245 + 0.105 = 0.35 P(Y=3) = 0.175 + 0.075 = 0.25 Show more…

Consider the random variables $X$ and $Y$ with joint density function $$ f(x, y)=\left\{\begin{array}{ll} x+y, & 0 \leq x \leq 1 ; 0 \leq y \leq 1 \\ 0, & \text { elsewhere. } \end{array}\right. $$ (a) Find the marginal distributions of $X$ and $Y$. (b) Find $P(X>0.25, Y>0.5)$.
