**Reiny**, Tuesday, August 18, 2009 at 5:26pmif you include the empty set and the entire set itself in the list of subsets there will be 2^5 or 32 subsets for 5 elements.

In general, if you have n elements in a set, there will be 2^n number of subsets including the null set and the entire set itself.

e.g. {A,B,C)

subsets : {},{A},{B},{C}, {A,B}, {A,C}, {B,C}, {A,B,C}

there would be 2^3 or 8 of them
