Question 950377: Please help me solve this, I know there is a calculation that can be done, but don't know what that is.
how many subsets and proper subsets are there fir {t,e,j,a,n,i,g,l}?
Answer by MathLover1(20850)   (Show Source):
You can put this solution on YOUR website! subsets and proper subsets are there fir {t,e,j,a,n,i,g,l}
Recall, the number of subsets for set  is  where  is the number of elements in set .
in your case  , so you will have  subsets
recall that the empty set is a proper subset of any nonempty set
recall that {a, b} is a proper subset of {a, b, c}, but {a, b, c} is not a proper subset of {a, b, c}
so, in your case there is 
all subsets and proper subsets of {t,e,j,a,n,i,g,l}:
