¿Q5?: (20 points total) Tree me. The probability model for discrete random variable A is: for a = -1 PA(a) = for a = 1 0 else The conditional probability model for discrete random variable B given A is: (3) PBiA (bla = -1) = AGAI for b=0 for b= 1 o else Pola(bla = 1) = for b=0 for b= 1 0 else (4) ON (a) (10pts) Find the joint PMF of A and B, PAB(a,b). Hint: draw a tree diagram for your joint experiment. (b) (10pts) If B = 1, what is the conditional variance of A given B = 1, i.e., Var(A B = 1).
