Suppose that n(u) = 200, n(a) = 135, n(b) = 105, and n( a ∩ b ) = 50.

find n( a c ∪ b ).a) 85b) 65c) 105d) 115e) 55

d) 115

Step-by-step explanation:

Given : n(U) = 200, n(A) = 135, n(B) = 105, and n( A ∩ B ) = 50.

To find :

Complement of A =

With the help pf the Venn diagram below, we have

Since , Only A = A-A ∩ B

i.e. Only A = n(A) - n( A ∩ B ) =135-50=85

Then,

Hence, the correct answer is d) 115 .

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
