How can you figure out how many rule combinations will be generated?

To determine the number of rule combinations generated, multiplying the number of labels of each type together is the correct approach. This is because each label type can independently influence the rule combinations. For instance, if there are three different types of labels, and each type has a certain number of labels, the total number of combinations is found by taking the product of the number of labels from each type.

This multiplication reflects the principle of combinations where each label from one type can combine with each label from the other types, leading to a total that is the product of the individual counts. For example, if there were 2 labels for type A, 3 labels for type B, and 4 labels for type C, the total combinations would be 2 x 3 x 4 = 24 different rule combinations.

In contrast, adding, subtracting, or dividing the number of labels does not account for the combinatorial nature of rules that involve multiple label types, which is why those methods would not yield the correct total of rule combinations.
