यदि (n\(A\cap B\)=48), (n\(A\cap C\)=41), (n\(B\cap C\)=39) और (n\(A\cap B\cap C\)=17) है, तो कम से कम दो समुच्चयों में आने वाले तत्व कितने हैं?
If (n\(A\cap B\)=48), (n\(A\cap C\)=41), (n\(B\cap C\)=39), and (n\(A\cap B\cap C\)=17), how many elements are in at least two sets?
Explanation opens after your attempt
B. (94)
Concept
At least two is ((48-17)+(41-17)+(39-17)+17=94). Find exactly two and then add the all-three part.
Why this answer is correct
The correct answer is B. (94). At least two is ((48-17)+(41-17)+(39-17)+17=94). Find exactly two and then add the all-three part.
Exam Tip
कम से कम दो (=(48-17)+(41-17)+(39-17)+17=94) है। ठीक दो निकालकर तीनों वाला भाग जोड़ें।
