In: Statistics and Probability
f(x1, x2) = 12x1x2(1-x2) , 0 < x1 <1 0 < x2 < 1
(ii) Calculate E(X1) and E(X2)
(iii) Are the variables X1 and X2 stochastically independent?
(iv) Given the variables in the question, find the conditional p.d.f. of X1 given 0<x2< ½ and the conditional expectation E[X1|0<x2< ½ ].
