यदि (n(U)=96), (n(A-B)=29), (n\(A\cap B\)=17) और (n(B-A)=22) है, तो वेन आरेख का बाहरी क्षेत्र कितना है?
If (n(U)=96), (n(A-B)=29), (n\(A\cap B\)=17), and (n(B-A)=22), what is the outside region of the Venn diagram?
Explanation opens after your attempt
A. (28)
Concept
The inside union is (29+17+22=68), so outside is (96-68=28). The outside region is found by subtracting the inside part from (U).
Why this answer is correct
The correct answer is A. (28). The inside union is (29+17+22=68), so outside is (96-68=28). The outside region is found by subtracting the inside part from (U).
Exam Tip
अंदर का संघ (29+17+22=68) है, इसलिए बाहर (96-68=28) है। बाहरी क्षेत्र (U) से अंदर का भाग घटाकर मिलता है।
