Final answer:
The probability rule that deals with the probability of an event occurring in a specific order each time is the permutation rule (option A).
Step-by-step explanation:
The probability rule that deals with the probability of an event occurring in a specific order each time is permutation rule (option A).
The permutation rule is used when the order of the events is important. It calculates the number of ways to arrange items from a set. For example, if you have 3 books and you want to arrange them on a shelf, the permutation rule would be used to calculate the number of possible arrangements.
