The random variables X and Y have the discrete probabilities P(X, Y)P(X, Y) listed below.
Assume that P(X, Y)=0 P(X, Y)=0 if not included here.
P(−1,1)=445, P(−1,0)=245, P(−1,−1)=345, P(0,1)=945, P(0,0)=645, P(0,−1)=745, P(1,1)=145 P(1,0)=545 P(1,−1)=845 P(−1,1)=445, P(0,1)=945, P(1,1)=145 P(−1,0)=245, P(0,0)=645, P(1,0)=545 P(−1,−1)=345, P(0,−1)=745, P(1,−1)=845
