To find the total number of people who prefer the seaside or an island, we can add the total preferences for both the seaside and the island across all activities.
From the table:
-
For the seaside:
- Hiking: 20
- Swimming: 53
- Total for seaside = 20 + 53 = 73
-
For the island:
- Hiking: 12
- Swimming: 40
- Total for island = 12 + 40 = 52
Now, we add the totals for the seaside and the island: Total = Seaside + Island = 73 + 52 = 125
Therefore, the total number of people who prefer the seaside or an island is 125.
