Question 1127959
<pre>
I'm afraid your answers are wrong.  The empty set is a subset of
every set.
</pre>
U = {0,1,2,3,4,5,6,7,8,9}
P= {1,3,5,7,9}
Q = {2,4,6}
R = {6,8}

1) Find all the subsets of Q = {2,4,6}
<pre>
You must list all 2³ or 8 subsets, including the IMproper one.

1. Ø
2. {2}
3. {4}
4. {6}
5. {2,4}
6. {2,6}
7. {4,6}
8. {2,4,6}   <-- that's the only IMproper subset because it is
                 not properly "sub" to {2,4,6}, for it is the
                 whole set. 
</pre>
2) Find all proper subsets of R = {6,8}
<pre>
You must list all subsets, except the IMproper one, {6,8}
1. Ø
2. {6}
3. {8}

Note that we do not include {6,8} for it is not properly "sub" to
{6,8}, for it is the whole set.
</pre>
I don’t understand the difference of a subset and proper subset?
<pre>
All subsets of a given set are proper subsets except the whole given
set itself.  The whole set is the only IMproper subset.
