How to determine direction of the current in the following circuit? Then, the following properties should hold true: The covariance between \(X\) and \(Y\) is a measure of the strength of the linear association or linear relationship between the variables. p_{_{Y,Z}}(y,z\mid \operatorname{Odd}(X)) & = \frac 1 4 \;\mathbf 1_{(y,z)\in \{(0,0),(0,2),(2,0),(2,2)\}} $$p_X(x\mid \operatorname{Even}(X)) = p(1-p)^{x/2-1}$$, 3) If $X$ is odd, $p_{X,Y}(x,2\mid \operatorname{Odd}(X))=$, $p_Y(2\mid \operatorname{Odd}(X)) = \frac 1 2 The variables are considered independent if: P(X = x, Y = y) = P(X = x)P(Y = y), for all x,y (discrete case) And Also, we need the variances \(Var(X)\) and \(Var(Y)\). We know that: $$ \begin{align*} Var\left(X\right)&=E\left(X^2\right)-\left[E\left(X\right)\right]^2\\ &=\left[0^2\times0.4+1^2\times0.3+2^2\times0.3\right]-{0.9}^2\\ &=0.69 \end{align*} $$, $$ \begin{align*} Var\left(Y\right)&=E\left(Y^2\right)-\left[E\left(Y\right)\right]^2 \\ &=\left[1^2\times0.2+2^2\times0.4+3^2\times0.4\right]-{2.2}^2\\ &=0.56 \end{align*} $$, $$ \begin{align*} Corr\left(X,Y\right)&=\frac{cov\left(X,Y\right)}{\sqrt{var\left(X\right)var\left(Y\right)}}\\ &=\frac{0.02}{\sqrt{0.69\times0.56}}\approx0.03 \end{align*} $$.
