Q57: (20 points total) Tree me. The probability model for discrete random variable A is: P.(a) = for a = -1 for a = 1 0 else (3) The conditional probability model for discrete random variable B given A is: PBlabla = -1) = GA for b=0 for b= 1 o else Pabla = 1) = 1 for b=0 for b= 1 0 else (4) (a)(10pts) Find the joint PMF of A and B, PAB(,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).
