Correct Answer
A. (6)
Concept
(n\(A\times B\)=n(A)n(B)=3\times2=6). In exams, first count the elements of both sets.
Why this answer is correct
The correct answer is A. (6). (n\(A\times B\)=n(A)n(B)=3\times2=6). In exams, first count the elements of both sets.
Exam Tip
(n\(A\times B\)=n(A)n(B)=3\times2=6) होता है। परीक्षा में पहले दोनों समुच्चयों के अवयव गिनें।
