For that if we write down the subsets of A then they are: 1) Null //subsets of length 0 2) {1}, {2},{3} //subsets of length 1 3) {1,2},{2,3},{3,1} //subsets of length 2 4) {1,2,3} //subsets of length 3 Null is a subset of A. So True You can directly conclude this because null is a subset of any set. 1 votes 1 votes Please log in or register to add a comment.
