Answer:
Option B). Venn diagram 2
Step-by-step explanation:
A class of 30 students took midterm science exams.
20 students passed chemistry exam, 14 passed physics and 6 students passed both physics and chemistry.
Since 6 students are common in both, so students who passed chemistry exam only will be = 20 - 6 = 14
And students who passed physics only = 14 - 6 = 8
So students who passed chemistry only are 14, students physics only are 8 and students who passed both the subjects are 6.
Moreover, students who couldn't pass any subject = 30 - (14 + 8 + 6) = 30 - 28 = 2
Option B) Venn diagram 2 is the correct option.
