WebThe probability that any subset of the variables will take on a particular joint assignment. For example, we can calculate that the probability P(Wealth=rich^ Gender=female) = 0:0362, by summing the two table rows that satisfy this joint assignment. Any conditional probability defined over subsets of the variables. Recall WebA contingency table provides a di erent way of calculating probabilities. The table helps in determining conditional probabilities quite easily. The table displays sample aluesv in relation to two di erent ariablevs that may be dependent or contingent on one another. Later on, we will use contingency tables again, but in another manner. Example 1 länsi uudenmaan säästöpankki lohjan konttori
