Making statements based on opinion; back them up with references or personal experience. The variables are considered independent if: P(X = x, Y = y) = P(X = x)P(Y = y), for all x,y (discrete case) And A value of \(\rho \text{ near } +1 \text{ or } -{{1}}\) indicates a high degree of linearity between \(X\) and \(Y\), whereas a value near 0 indicates that such linearity is absent.

Lets now calculate the means of \(X\) and \(Y\): $$ \begin{align*} E\left(X\right)&=\sum_{x=1}^{4}{xf_X\left(x\right)}\\ &=\sum_{x=1}^{4}{x\frac{2x^2+9}{96}}\\ &=\left(1\right)\frac{11}{96}+\left(2\right)\frac{17}{96}+\left(3\right)\frac{27}{96}+\left(4\right)\frac{41}{96}\ \\ &=\frac{11}{96}+\frac{34}{96}+\frac{81}{96}+\frac{164}{96}\\ &=\frac{145}{48}\ \end{align*} $$, $$ \begin{align*} \sigma_X^2&=Var\left(X\right)=\sum_{x=1}^{4}{x^2f_X\left(x\right)-\left[E\left(X\right)\right]^2}\\ &=\sum_{x=1}^{4}{x^2\frac{2x^2+9}{96}}-\left(\frac{145}{48}\right)^2\\ &=\left(1\right)^2\frac{11}{96}+\left(2\right)^2\frac{17}{96}+\left(3\right)^2\frac{27}{96}+\left(4\right)^2\frac{41}{96}-\left(\frac{145}{48}\right)^2\\ &=\frac{163}{16}-\left(\frac{145}{48}\right)^2=1.062\ \end{align*} $$, $$ \begin{align*} \mu_Y&=E\left(Y\right)=\sum_{y=1}^{2}{yf_Y\left(y\right)}\\ &=\sum_{y=1}^{2}{y\frac{12y+30}{96}=\left(1\right)\frac{42}{96}+\left(2\right)\frac{54}{96}\ }\\ &=\frac{42}{96}+\frac{108}{96}\\ &=\frac{25}{16}\ \end{align*} $$, $$ \begin{align*} \sigma_Y^2&=\sum_{y=1}^{2}{y^2f_Y\left(y\right)-\left[\mu_Y\right]^2}\\ &=\sum_{y=1}^{2}{y^2\frac{12y+30}{96}-\left(\frac{25}{16}\right)^2}\\ &=\left(1\right)^2\frac{42}{96}+\left(2\right)\frac{54}{96}-\left(\frac{25}{16}\right)^2\\ &=\frac{42}{96}+\frac{216}{96}-\frac{625}{256}=\frac{43}{16}-\frac{625}{256}\\ &=\frac{63}{256} \end{align*} $$. Both the probabilities must be multiplied be calculated by adding a column for xf ( X ) calculations a. When the covariance is positive; it means we have a positive association between the random variables \(X\) and \(Y\), while a negative covariance implies a negative association exists between the variables \(X\) and \(Y\). The (marginal) probability mass function of \(Y\) is: $$ \begin{array}{c|c|c|c} \text{Y} & {1} & {2} & {3}\\ \hline {{P}({Y}={y})} & {0.2} & {0.4} & {0.4} \end{array} $$, $$ E\left(Y\right)=1\times0.2+2\times0.4+3\times0.4=2.2 $$, $$ Cov\left(X,Y\right)=2-0.9\times2.2=0.02 $$.
