What are the number of subsets of the set A = {a, b, c, d, e, f} andOf set B = {a, b, c, d, e, f, g, h, i, j}?

no of subsets of A=2^6 =64


no of subsets of B=2^10=1024

What are the number of subsets of the set A = {a, b, c, d, e, f} andOf set B = {a, b, c, d, e, f, g, h, i, j}?
2^6 = 64 and 2^10 = 1024
Reply:You just need to know that for a set of n items (n%26gt;=0) there are exactly 2^n subsets;


so set A has 2^6 = 64 subsets,


and set B has 2^10 = 1024 subsets.


(NB Among the subsets in each case are the empty set and the complete set, i.e. A or B, resp.)
