This formula correctly places the sum of the scores in parentheses before dividing by 3, ensuring that the sum is divided by 3 before any further operations are performed. Choices A and B incorrectly separate the last score (z) from the other scores, potentially resulting in a different calculation than intended. Choice D uses a colon instead of a division sign, which is not a valid mathematical operator.
