Let U be the universal set. If $B \subset A$ , describe the following set. $B \cap \bar { A }$
A) $\bar { B }$
B) U
C) A
D) $\bar { A }$
E) $\varnothing $

Question

Quizplus · Accepted Answer

Given that $B \subset A$, the set $B \cap \bar{A}$ represents the intersection of B with the complement of A. Since B is a subset of A, there are no elements in B that are outside of A. Therefore, the intersection of B with the complement of A (which consists of all elements not in A) is the empty set, denoted by $\varnothing$.
