In case you dont know how to subtract its 416. A.
To find the number of people who named neither blue nor red as their favorite color, we first need to find the number of people who named blue as their favorite color and the number of people who named red as their favorite color.
According to the survey, 1 out of 3 people named blue as their favorite color. Since there were 1,092 people included in the survey, we can calculate the number of people who named blue as their favorite color as follows:
1/3 * 1092 = 364 people
Similarly, 2 out of 7 people named red as their favorite color. Using the same approach, we can calculate the number of people who named red as their favorite color as follows:
2/7 * 1092 = 312 people
Now, to find the number of people who named neither blue nor red as their favorite color, we subtract the sum of people who named blue and people who named red from the total number of people included in the survey:
1092 - (364 + 312) = 1092 - 676 = 416 people
Therefore, the correct answer is A. 416 people.
