網頁Propositional Logic Question 1 Suppose that the statement p → ¬q is false. Find all combinations of truth values of r and s for which (¬q → r) ∧ (¬p ∨ s) is true. Question 2 If the statement q ∧ r is true, determine all combinations of truth values for p and s ... 網頁They both have the same cardinality (continuum). I suggest proving it this way: Prove N N = 2 N . An explicit bijection isn't hard to find here. Hint: instead of thinking of them as spaces of functions, think of them as finite sequences, the first sequences of natural numbers, the second seconds from {0, 1}.

網頁R / Q and R are both size continuum. So by assuming as vector spaces over the Q they must have continuum size bases. We know that if two vector spaces have bases of the same size then they are isomorphic.

網頁The cartesian product of several input sets is a larger set that contains every ordered combinations of all the input set elements. The cartesian product of three sets P, Q, and R can be written as: P × Q × R = { (a,b,c): a ∈ P, b ∈ Q, c ∈ R } Let us consider the example of three sets A, B and C, where A = {2,3} , B = {x,y}, and C = {5,6}.
