Question

Let $A=\{a,b,c,d\},B=\{a,b,c\},C=\{b,d,e\}$ then, find the sets D and E satisfying following condition

$C\supset E,B\cap E=\varphi$

Answer 1

Set E should be such that it is a subset of B and no elements should be common in B and E
Since the common elements of B and C is just b, E cannot have the element b
So, one of the possibilities of set E is { $e$}
