Suppose that X and Y have joint mass function as shown in the table below. (Here, X takes on possible values in the set {-2, 2}, Y takes on values n the set {-2, 0, 2, 3}.) Compute P(| X + Y^2|

Solution

b=Fxy=.18*.18=.0324

d-marginal distribution of x at x=-2is = .04+.08+.12+.16= .4

@x=-2 is = .06+.12+.18+.24=.6
