Subset homework problem

  1. Sep 1, 2012 #1
    1. The problem statement, all variables and given/known data
    The problem wants me to give an example of two sets that satisfy this condition

    A∩P(A)ε B

    2. Relevant equations


    3. The attempt at a solution
    For my example I used this example
    ∅ε B

    Therefore A∩P(A)ε B
    is this a correct example?

    Re: subsets??

    im allowed to make up a set for set B. But considering that A∩P(A)=∅ then I thought that the empty set has to be an element in set B.

    Re: subsets??

    It seems to be correct.
