To find the probability of Brandy's classmates going on vacation this summer, we can add up the number of classmates who took a vacation (9+6+5 = 20) and divide it by the total number of classmates (26).
Probability = Number of classmates who vacationed / Total number of classmates
Probability = 20 / 26 = 0.7692
So the probability of Brandy's classmates going on vacation this summer is approximately 0.7692 or 76.92%.
Therefore, the answer is:
C. 9/26
