Question
We are currently on set operations and ven diagrams and I’m a little confused about the relationship between
n(A union B), n(A), n(B), and n(A intersection B)
The problem is this:
n(U)= 60, n(A)= 27, n(B)=22 and n(A intersect B)= 5
Find n(A’ union B)
the universal letter is throwing me off and confusing
I appreciate your time
Expert Solution
Step 1
To count the number of elements in A' union B using the given information
Step 2
In words, there are totally 60 elements ( because U , the universal set contains 60 elements. ) A contains 27 elements, so A' (the complement of A) contains 60-27 = 33 elements.
