Prove by induction that if A and B are finite sets, A with n elements and B with m elements, then A x B has nm elements. Also, prove by induction the corresponding results for k sets.
Set Proof:
1. Prove that if S and T are finite sets with |S| = n and |T| =
m, then |S U T| <= (n + m)
2. Prove that finite set S = T if and only if (iff) (S
Tc) U (Sc T) =

Let P(n) be the proposition that a set with n elements has 2" subsets. What would the basis step to prove this proposition PO) is true, because a set with zero elements, the empty set, has exactly 2° = 1 subset, namely, itself. 01 Ploi 2. This is not possible to prove this proposition. 3. po 3p(1) is true, we need to show first what happens a set with 1 element. Because, we can't do P(O), that is not allowed....
In: the set {1,...,n} consisting of the positive integers 1 up to n (n included). P(S): the power set of a set S; namely, the set of all subsets of S. P*(S): = P(S) - {@}; namely, the set of all non-empty subsets of S. The following question is a challenging one! As a start, may be you try this question for small values of n, say n=1,2,3. Can you make a guess? (1) We all know that P*(On) has...

Let S be a finite set with cardinality n>0. a. Prove, by constructing a bijection, that the number of subsets of S of size k is equal to the number of subsets of size n- k. Be sure to prove that vour mapping is both injective and surjective. b. Prove, by constructing a bijection, that the number of odd-cardinality subsets of S is equal to the number of even-cardinality subsets of S. Be sure to prove that your mapping is...
