I need some help on subsets because this problem I have is giving me issues. If any of you could help me that would be wonderful. Write all of the subsets of the following set: {1,2,5}

The empty set. The three sets with one element in each. The three sets with exactly two elements in it. The full set.
So something like this? A = {1} B = {2} C= {5} D = {1, 2} E = {2, 5} Full Set = {1, 2, 3, 4, 5}

In general, if a set has n members, then it has subsets, including the empty set and the entire set. Here n= 3 so there are subsets.
