Question 950364

all subsets of K = { e, f, g, h }

Recall, the number of subsets for set {{{A}}} is {{{2^(n(A))}}}where {{{n(A)}}} is the number of elements in set {{{A}}}.
in your case {{{n(A)=4}}}, so you will have {{{2^4=16}}}subsets
 
recall that empty set is subset of each set

all subsets of K:

1.{ }
2.{e }
3.{f }
4.{g }
5.{ h}
6.{e,f }
7.{e,g }
8.{e,h }
9.{f,g }
10.{f,h }
11.{g,h }
12.{e,f,g }
13.{e,f,h }
14.{e,g,h }
15.{f,g,h }
16.{e,f,g,h }
