Use the table to answer the question.
The table is down there.
Hiking: 45 mountains, 20 seaside, 12 island.
Swimming: 12 mountains, 53 seaside, 40 island.
Given the data in the table, what is the relative frequency that people who prefer island vacations also prefer swimming?Round the percentage to the nearest tenth.
To find the relative frequency that people who prefer island vacations also prefer swimming, we need to divide the number of people who prefer both swimming and island vacations by the total number of people who prefer island vacations.
From the table, we can see that the number of people who prefer both swimming and island vacations is 40.
The total number of people who prefer island vacations is 12 + 40 + 53 = 105.
Therefore, the relative frequency can be calculated as:
Relative frequency = (Number of people who prefer both swimming and island vacations) / (Total number of people who prefer island vacations)
= 40 / 105
≈ 0.381
≈ 38.1%
So, the relative frequency that people who prefer island vacations also prefer swimming is approximately 38.1%.
