Option B) 15 is the total number of students in Jackson’s class.
Step-by-step explanation:
From the given Venn diagram,
we can determine the following information :
- The number of students in Band = 10 students.
- The number of students in Orchestra = 8 students.
- The number of students in both = 5 students.
- The number of students in neither band nor orchestra = 2 students.
To find the total number of students :
The formula to find the total number is given by,
Total = Group 1 + Group 2 - Both + Neither
Here, we have group 1 as band and group 2 as orchestra.
Total number of students = 10 + 8 - 5 + 2 ⇒ 15 students. (option B)
