□%
To find the relative frequency that people who prefer island vacation also prefer swimming, we need to calculate the proportion of people who prefer swimming on the island compared to the total number of people who prefer island vacation.
Total number of people who prefer island vacation = 12 (island)
Number of people who prefer swimming on the island = 40 (island)
Relative frequency = (Number of people who prefer swimming on the island / Total number of people who prefer island vacation) * 100
Relative frequency = (40 / 12) * 100
Relative frequency = 3.33 * 100
Relative frequency = 33.3%
Therefore, the relative frequency that people who prefer island vacation also prefer swimming is approximately 33.3%.
