Run 100 experiments and argue that the observed data implies independence between the events A={Coin=Head} and B={Die=3}, i.e., P(A⋂B) = P(A) P(B), approximately. Using the 1‐6 flat with p=0.5, we have the above situation. We have chosen the setting of X == A == Coin to be P(X=1) = 0.5 and P(X=0) = 0.5, Further, we have chosen the setting of Y == B == Die to be P(Die = d) = 0.16667 for all d. Since we have the empirical distributi...
