Question 202665
"N" stands for the set of Natural numbers which are: {1, 2, 3, 4, 5, ...}.<br>
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}<br>
Since there is an element of A, 19, which is not in set B:<ul><li>A = B is <b>false</b>.</li><li>A is a subset of B is <b>false</b>.</li></ul>
But all the elements of B are also elements of A so B is a subset of A.
