यदि (n(U)=88), (n(A-B)=24), (n\(A\cap B\)=13) और (n(B-A)=26) है, तो वेन आरेख का बाहरी क्षेत्र कितना है?
If (n(U)=88), (n(A-B)=24), (n\(A\cap B\)=13), and (n(B-A)=26), what is the outside region of the Venn diagram?
Explanation opens after your attempt
A. (25)
Concept
The inside union is (24+13+26=63), so outside is (88-63=25). The outside region is always found by subtracting the inside part from (U).
Why this answer is correct
The correct answer is A. (25). The inside union is (24+13+26=63), so outside is (88-63=25). The outside region is always found by subtracting the inside part from (U).
Exam Tip
अंदर का संघ (24+13+26=63) है, इसलिए बाहर (88-63=25) है। बाहरी क्षेत्र हमेशा (U) से अंदर का भाग घटाकर मिलता है।
