Homework Help: Maths - Sets

Posted by Veronica on Sunday, May 4, 2008 at 8:23am.

While I was doing some exercises on sets

A question accured " M = {a,e,i,o,u}
a) how many subsets are there of M ?

When I did it was two , because a subset from my knowledge is that all of the elements in the set are there with the empty set

The answer was said at the back of the book , that it was wrong and the answers were "

{ a, e , o i u } ( a , o , e } {a , e ,u } ... etc , all of the answers that should be the " proper set " of M

can someone clarify wheither it's me who's wrong or the book

thanks
