Correct Answer
A. ({1,2,3,6,7,8,9,10})
Concept
(A'={4,5,6,7,8,9,10}) and \(A'\cap B={4,5}\). Its complement is ({1,2,3,6,7,8,9,10}).
Why this answer is correct
The correct answer is A. ({1,2,3,6,7,8,9,10}). (A'={4,5,6,7,8,9,10}) and \(A'\cap B={4,5}\). Its complement is ({1,2,3,6,7,8,9,10}).
Exam Tip
(A'={4,5,6,7,8,9,10}) और \(A'\cap B={4,5}\) है। इसका पूरक ({1,2,3,6,7,8,9,10}) है।
