Answer: 1130 students
Step-by-step explanation:
as given math and chemistry n(A∩B) =70
so enrollment in maths n(A)= 700
and enrollment in chemistry n(B) = 500
as we know
n(A∪B) = n(A) + n(B) - n(A∩B)
= 700 + 500 - 70
= 1130
so at least 1130 students take one of these two subjects.
hence option 2 is correct.
