Without writing them all out, what is the number of subsets of set
A ={king, queen, knight, prince, princess, duke}?

In general , the number of subsets of n elements is 2^n, including the null set and the entire set.
since you have 6 elements, there will be 2^6 or 64 elements.

should have been...
64 subsets, (not elements)
