( EV ) is the probability mass function for a when we aren t at! First, to find the conditional distribution of X given a value of Y, we can think of fixing a row in Table 1 and dividing the values of the joint pmf in that row by the marginal pmf of Y for the corresponding value. Find the conditional PMF of X given Y = 0 and Y = 1, i.e., find P X | Y ( x | 0) and P X | Y ( x | 1). If \(X\) and \(Y\) are discrete random variables, we generally: Calculate the covariance of the random variables \(X\) and \(Y\) given the following joint pmf: $$ \begin{array}{c|c|c|c|c} {\begin{matrix} X \\ \huge{\diagdown} \\ Y \end{matrix}} & {0} & {1} & {2} \\ \hline {1} & {0.1} & {0.1} & {0} \\ \hline {2} & {0.1} & {0.1} & {0.2} \\ \hline {3} & {0.2} & {0.1} & {0.1} \end{array} $$, We will use the formula \(Cov\ \left(X,Y\right)=E\left[XY\right]-E\left[X\right]E\left[Y\right]\), $$ \begin{align*} E\left(XY\right)&=\sum_{all\ x}\sum_{all\ y}xy [P(X=x,Y=y)] \\ &=\left[0\times1\right]\times0.1+\left[1\times1\right]\times0.1+\ldots+2\times3\times0.1=2 \end{align*} $$.
