what is the formula for finding the subset?


Sagot :

I assume the question asks for the formula for finding the number of subsets in a set.

This is the formula for finding the number of subsets in a set.

        [tex] 2^{n(A)}[/tex]
             - n(A) means number of elements in A.

Ex.  
        A = {a, b, c}
There are 3 elements, so  [tex] 2^{3} [/tex] = 8 subsets all in all
Proof:
Subsets:     B = {a}   C = {b}  D = {c}  E = {a, b}    F= {a, c}    G = {b,c}
                   H = {a, b, c}   I = { }

(Though, you can just make the formula, [tex] 2^{n} [/tex] where n is the number of elements in the set)
