Answer

Answer:

166

Explanation:

Step1: Identify total - people concept

The total number of people polled is the grand - total in the two - way table.

Step2: Locate grand - total

In the two - way table, the grand - total is the value in the bottom - right cell. Here, the sum of all the individual counts (students and workers who take bus or subway) gives the total number of people polled. We can calculate it as (48 + 118=166) or (69 + 97 = 166).
