यदि (n\(A\cap B\)=29) और (n\(A\cap B\cap C\)=12) है, तो केवल (A) और (B) में लेकिन (C) में नहीं कितने हैं?
If (n\(A\cap B\)=29) and (n\(A\cap B\cap C\)=12), how many are only in (A) and (B) but not in (C)?
Explanation opens after your attempt
A. (17)
Concept
For only (A) and (B), (29-12=17). A pairwise intersection includes the common part of all three.
Why this answer is correct
The correct answer is A. (17). For only (A) and (B), (29-12=17). A pairwise intersection includes the common part of all three.
Exam Tip
केवल (A) और (B) के लिए (29-12=17) होगा। जोड़ी वाले प्रतिच्छेद में तीनों का साझा भाग शामिल रहता है।
