Step-by-step explanation:
From the given conditional relative frequency table , it can be seen that
The probability of person who who did vote and work on election day= 0.64
If the total number of person voted = 50
Then, the number of person who did vote and work on election day=![0.64\times50=32](/tpl/images/0306/0474/d160a.png)
The probability of person who who did not vote but did work on election day= 0.4
If the total number of person did not vote= 85
Then, the number of person who did vote but did work on election day=![0.4\times85=34](/tpl/images/0306/0474/0c9dd.png)
Now, the number of people in the survey worked on election day=![32+34=66](/tpl/images/0306/0474/083d3.png)
