Answer: A. That order is taken into account (consider rearrangements of the same items to be different sequences).
Step-by-step explanation:
The combination is usually given by the formula below:
C n,x = n! / x! (n-x)!
We should note that the requirements for a combination rule include:
• That r of the n items are selected (without replacement).
• That there be n different items available.
• That order is not taken into account (consider rearrangements of the same items to be the same).
Therefore, the option that is not a requirement of the Combinations Rule, , for the items that are all different will then be option A"That order is taken into account (consider rearrangements of the same items to be different sequences).
