वेन आरेख में (\(A\cup B\)\cap\(A\cup B^c\)) किसके बराबर है?

In a Venn diagram, what is (\(A\cup B\)\cap\(A\cup B^c\)) equal to?

Explanation opens after your attempt
Correct Answer

A. (A)

Step 1

Concept

By distributive law, (\(A\cup B\)\cap\(A\cup B^c\)=A\cup\(B\cap B^c\)=A). This is because \(B\cap B^c=\varnothing\).

Step 2

Why this answer is correct

The correct answer is A. (A). By distributive law, (\(A\cup B\)\cap\(A\cup B^c\)=A\cup\(B\cap B^c\)=A). This is because \(B\cap B^c=\varnothing\).

Step 3

Exam Tip

वितरण नियम से (\(A\cup B\)\cap\(A\cup B^c\)=A\cup\(B\cap B^c\)=A)। क्योंकि \(B\cap B^c=\varnothing\)।
