Question

Which of the following sets is equal to A = {3, 4, 7, 9}? B = {4, 4, 3, 8} C = {3, 9} D = {9, 7, 3} E = {9, 4, 7, 3}

Answer 1

E = {9, 4, 7, 3}

Explanation:

If two sets are equal, then they have the same number of elements and the same elements.

The given set is A = {3, 4, 7, 9}

The set that has the same elements as A is E = {9, 4, 7, 3}

The two set have the elements 3, 4, 7, 9.

Over here the order does not matter.
