The following is a proof that ``For all sets A and B, P(A^ B) ≤ P(A) ^P(B)". Fill in the blanks.
Proof:
Suppose that A and B are any sets, and suppose that S is a set such that SEP(ANB). By definition of power sets, then SCAN B..
Since An BCA, then
. Similarly, since An BCB, then
and so,
Hence, by definition of
Therefore, P(ANB) ≤ P(A) ~P(B).
