SOLUTION: n(U) = 150, n(A) = 90, n(B) = 70, n(A U B)’ = 30 Using the information above find n(A ∩ B)

Algebra ->  sets and operations -> SOLUTION: n(U) = 150, n(A) = 90, n(B) = 70, n(A U B)’ = 30 Using the information above find n(A ∩ B)       Log On

.
How the sets  U,  A  and  B  are inter-related?
Who is a sub-sit in whom?
Without this information your problem does not make sense.

And what is this stroke in the formula n(A U B)’ = 30 ?

Can you formulate the problem accurately?
