Question details

8. Consider the function given below: f(xly) =-, x=0,1, y20. r! i) Show that for each fixed y. /(x |y) is a pd.f, the conditional pd.f of ar.v. X, given that another rv. Y equals y. ii) If the marginal pd.f. of Y is Negaative Exponential with parameter λ-1, what is the joint p.d.f.of X,Y? ii) Show that the marginal p.d.f. of X is given by f(x)- =151 x=0.1, 2, ,
