Question

which of the following sets are equivalent A={1,2,3,4} B={3,1,2,4}​

Answer 1

Explanation:

A={1,2,3}

B={2,1,3}

A=B(Both set A and B contain same element )

Answer 2

Explanation:

Given sets are A={1,2,3,4} B={3,1,2,4}

elements in A=elements in B

n(A)=n(B)

A and B are equivalent sets

and Every element of A is in B and every

element of Bis in A

A and B equal sets.

Equivalent sets:-

If n(A)=n(B) then A and B are equivalent sets

and

Equal sets:-

every element of A is in B and every element of B is in A then A and B are equal sets.
