Final answer:
To find the probability of obtaining a score of 9 without a distribution, we need more information.
Step-by-step explanation:
To find the percentage of the time someone will obtain a score of 9, you need to refer to the given distribution. However, the distribution provided in the question seems to be missing. It is important to have access to the distribution to accurately calculate the probability. Without the distribution, it is not possible to calculate P(9). Please provide the distribution to proceed with the calculation.
