hi.. :)

Just use the Bayes Rule to get the required probability>

P(X1=2 given that X2=1)= P(X1=2)*P(X2=1 given that X1=2)
                                  ------------------------------------
                                P(X1=2)*P(X2=1 given that X1=2) + P(X1=1)*P(X2=1 given that X1=1)

                                 = 1/3
