Question 202665: ) For sets A and B, determine whether A = B, A is a subset of B, or B is a subset of A

A = {x| x є N and 13 < x < 20}
B = {14, 15, 16, 17, 18}

"N" stands for the set of Natural numbers which are: {1, 2, 3, 4, 5, ...}.

So set A is the set of Natural numbers which are between 13 and 20. Now we can list the elements of set A:
A = {14, 15, 16, 17, 18, 19}

Since there is an element of A, 19, which is not in set B:
  • A = B is false.
  • A is a subset of B is false.

But all the elements of B are also elements of A so B is a subset of A.
