Discrete Math: Cardinality

Hi there,

I'm terrible at proving things, so I need a little help regarding
cardinality. (no, it's not for my homework assignment, I'm a curious
person. ;-)

If Set A has n members, the cardinality of P(A) is 2^n.

How do I prove this?

Any help is appreciated. Thank you very much.
