Question 482658
<pre>
Problem says this, and it is a multiple choice question:
Given the following sets, select the statement below that is NOT true.
A = {b, l, a, z, e, r} 
B = {b, a, l, e} 
C = {a, b, l, e} 
D = {l, a, b} 
E = {a, b, l} 

You need to learn the difference betweeen &#8834; and &#8838;.

It's like the difference between < and &#8804;.  A line under either symbol
means "EQUALITY IS ALLOWED BUT NOT REQUIRED",  When there is no line
underneath, it means "EQUALITY IS NOT ALLOWED".


Multiple choice possibilities:
1. E &#8834; A, TRUE because "a,b,&l" are all part of but not all of "b,l,a,z,&e" 
2. C &#8834; A, TRUE because "a,b,l,&e" are all part of but not all of "b,l,a,z,&e  
3. D &#8838; B, TRUE because "l,a,&b" is part of or all of "b,a,l,&e".  
4. C &#8834; B, FALSE because "a,b,l,&e" is ALL OF, not just part of "b,a,l,&e"
5. D &#8834; A, TRUE because "l,a,&b" are all part of but not all of "b,l,a,z,&e"
