Suppose that X and Y have a discrete joint distribution for which the joint probability mass function is defined as follows: pX,Y(k,l)= c|k+l|, for k=1,0,1,and l=1,0,1; 0, otherwise. (a) Find c. (b) Find the marginal probability mass function pX(·) for X. (c) Compute P(|X - Y | less than or equal 0.9).
