I need to know if the following questions are true or false

Answer:
see the attachment
Step-by-step explanation:
(a) S1 is the set of all subsets of {t, u, v}. There are 2^3 = 8 subsets, the EMPTY set being one of them. They are listed in the attachment.
It seems likely your answer will need to match that shown in the attachment:
{EMPTY, {t}, {u}, ... , {t, u, v}}
where the elements of multi-element sets are listed separately: {t, u}, not {tu}.
__
(b) S2 is the set S1 with <em>w</em> added to each subset. (see the attachment for a listing)
__
(c) Correct, the sets are disjoint, since every set in S1 is different from every set in S2.
__
(d) Each set has 8 elements; the sets are the same size. You know this because you created set S2 from set S1. (See (b), above.)
__
(e) The sets are disjoint (see (c)), so the total number of elements in their union is the total of the numbers of elements in each set: 8 + 8 = 16.
__
(f) P(A) is undefined here, so none of these questions can be answered.
