Rework problem 2 from section 3.4 of your text, involving probabilities on a tree diagram. Construct a copy of figure 3.16 in your text, where the first outcome is one of X and Y the second outcome is one of A and B if the first outcome is X, and one of A, B, and C if the first outcome is Y. Use the following probabilities instead of those given in your text:Pr[X]=0.6Pr[Y]=0.4Pr[A|X]=0.8Pr[B|X]=0.2Pr[A|Y]=0.4Pr[B|Y]=0.4Pr[C|Y]=0.2 Find the following missing probabilities: (1) Pr[A]=  (2) Pr[X|A]=    (3) Pr[Y|B]=  (4) Pr[B|Y]=
