Cardinality of sets |
2001-11-19 |
|
From Tania:
- Show that the cardinality of P(X) (the power set of X) is equal to the cardinality of the set of all functions from X into {0,1}.
- Show that (the cardinality of the natural numbers set) |N| = |NxNxN|.
- Show that the cardinality of the set of prime numbers is the same as the cardinality of N+
