Suppose the possible values of X are {xi}, the possible values of Y are {yj}, and the possible values of X + Y are {zk}. Let Ak denote the set of all pairs of indices (i,j) such that xi+yj =zk;thatisAk ={(i,j):xi+yj =zk} a. Argue that b. Argue that P{X+Y=zk}= ? P{X=xi,Y=yj} (i,j )∈Ak E[X+Y]=? ? (xi+yj)P{X=xi,Y =yj} k (i,j )∈Ak c. Using the formula in b, argue that E[X+Y]=??(xi+yj)P{X=xi,Y =yj} ij d. Show that P(X =xi)=?P(X =xi,Y =yj),P(Y =yj)=?P(X =xi,Y...
