Question

Match List I with List II and select the correct answer using the codes given below for the lists
Here $A^{\prime }$ is the complement set of $A$, $E$ is the universal set and $\Phi$ is an empty set
Codes:

	A	B	C	D
(a)	4	1	2	3
(b)	4	3	2	1
(c)	2	3	4	1
(d)	2	1	4	3

Answer 1

$\left(A\right)(E-A)\cup (E-A^{\prime })=A\cup A=E$

$\left(B\right)E-(A\cup A^{\prime })-(A\cap A^{\prime })$
$=E-(E-\varphi )$
=$E-E+\varphi =\varphi$

$\left(C\right)E\cap (A-A^{\prime })\cup A$
$=\{E\cap A\}\cup A=A\cup =A$

$\left(D\right)\{E-\varphi )\cup (\varphi -E)\}-A$

=$\{E\cup \varphi \}-A=E-A=A^{\prime }$
