Trường hợp C. Sắp xếp theo một tiêu chuẩn duy nhất là chúng ta phải thực hiện thao tác trên

C đó bạn

C1 :A = ( 9;10;11;12;13)

C2 : A = ( x\(\in\) N / 8<x<14 )

a: \(n\left(A\cap B\right)< =n\left(A\right)\le n\left(A\cup B\right)\)

b: \(n\left(A\ B\right)< =n\left(A\right)+n\left(B\right)< =n\left(A\cup B\right)\)
