List all the subsets of {2, o, t}.

To list all the subsets of a given set, we can use the concept of power set. The power set of a set is a set of all possible subsets of that set. Here's how to find all the subsets of the set {2, o, t}:

1. Start with an empty set {} as the first subset.

2. Add the first element of the original set {2} to the empty set, making it {2}. Now we have the subsets {}, {2}.

3. Add the second element of the original set {o} to each of the subsets from step 2. This gives us the subsets {}, {2}, {o}, {2, o}.

4. Add the third element of the original set {t} to each subset from step 3. This gives us the subsets {}, {2}, {o}, {2, o}, {t}, {2, t}, {o, t}, {2, o, t}.

So, the subsets of the set {2, o, t} are: {}, {2}, {o}, {2, o}, {t}, {2, t}, {o, t}, and {2, o, t}.
