To find the probability of Brandy's classmates going on vacation, we need to add up the number of classmates who went on vacation (9 beach + 6 mountains + 5 cruise = 20) and then divide by the total number of classmates (26).

So the probability is 20/26 which simplifies to 10/13.

Therefore, the answer is B) 10/13.
