Given the statement:
"all of the elements which are not in set A but are in set B"
Let's determine the expression that represents the above statement.
Here, we have:
All of the elements not in set A ==> A'
All of the elements which are not in set A but are in set B ==> A' ∩ B
Therefore, the expression that matches the given statement is:
(A' ∩ B)
ANSWER:
(A' ∩ B)
