    The first column sum is the probability that x =0 and y equals any of the values it can have – that is, the column sum 6/9 is the marginal probability that x=0. If we want to find the probability that y =0 given that x =0, we compute the fraction of the probabilities in the x =0 column that have the value y =0, which is 4/9 ÷ 6/9 = 4/6.
