Suppose that n(u) = 200, n(a) = 105, n(b) = 110, and n( a ∩ b ) = 30. find n( a c ∪ b ). a) 80 b) 110 c) 125 d) 95 e) 75 f) none of the above.

Option c -

Step-by-step explanation:

Given : Suppose that n(U) = 200, n(A) = 105, n(B) = 110, and n(A∩B) = 30.

To find : The value of ?

Solution :

n(U) = 200, n(A) = 105, n(B) = 110, and n(A∩B) = 30

We know that,

and

Now,  

Therefore, option c is correct.
