Greek Yogurt Substitute, \end{equation} Each car that is being repaired . Intuitively, two random variables are independent if the realization of one does not affect the probability distribution of the other. At this point, we can calculate the covariance for this function: $$ \begin{align*} Cov\left(X,Y\right)&=E\left[XY\right]-E\left[X\right]E\left[Y\right]\\ &=\frac{1}{3}-\frac{11}{18}\times\frac{5}{9}=-\frac{1}{162} \end{align*} $$, $$ \begin{align*} \rho&=\frac{cov\left(X,Y\right)}{\sqrt{Var\left(X\right)Var\left(Y\right)}}\\ &=\frac{-\frac{1}{162}}{\sqrt{\frac{23}{324}\times\frac{13}{162}}}=-0.082 \end{align*} $$.
