To determine the total number of people who were polled, we need to look at the row totals for both students and workers.
1. Counting Students:
- The number of students who took the bus: 27
- The number of students who took the subway: 21
- Total students = 27 (bus) + 21 (subway) = 48
2. Counting Workers:
- The number of workers who took the bus: 42
- The number of workers who took the subway: 76
- Total workers = 42 (bus) + 76 (subway) = 118
3. Total People Polled:
- Total people = Total students + Total workers
- Total people = 48 (students) + 118 (workers) = 166
Thus, the total number of people polled is 166.
