make it 5 sentences.
The probability of landing on a gray section of the spinner is 2 out of 3, since there are 2 gray sections out of a total of 3 sections on the spinner. The probability of rolling a sum of 9 with two dice is 4 out of 36, as there are 4 ways to roll a sum of 9 out of 36 possible outcomes. To find the overall probability, we multiply the two probabilities together: (2/3) * (4/36) = 8/108 = 1/13. Therefore, the probability that Nikki lands on a gray section of the spinner and rolls a sum of 9 with the two dice is 1 out of 13.
