Question 448585
I don't understand this problem. 
Given That A= {a,b,c} 
1.)List all of the subsets of A that have exactly one element.
 <pre><font face = "consolas" color = "indigo" size = 4><b>
{a} is a subset of {a,b,c} and it has has exactly one element.
(b) is a subset of {a,b,c} and it has has exactly one element.
(c) is a subset of {a,b,c} and it has has exactly one element.

</pre></font></b>
2.)List all of the subsets of A that have exactly two elements.
 <pre><font face = "consolas" color = "indigo" size = 4><b>

{a,b} is a subset of {a,b,c} and it has has exactly two elements.
(a,c) is a subset of {a,b,c} and it has has exactly two elements.
(b,c) is a subset of {a,b,c} and it has has exactly two elements.
