Discrete Math: Cardinality
Posted:
Oct 18, 1999 2:42 PM


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.
