Is the set NU (T, e,i) counta ble? Select one a. uncountable b. finite c. countably infinite
b and c please explian thx i post the question from the book Let 2 be a non-empty set. Let Fo be the collection of all subsets such that either A or AC is finite. (a) Show that Fo is a field. Define for E e Fo the set function P by ¡f E is finite, 0, if E is finite 1, if Ec is finite. P(h-10, (b) If is countably infinite, show P is finitely additive but not-additive. (c)...
From the class Introduction to Abstract Algebra on the section of countable and uncountable sets 3. Let X and Y be two nonempty finite sets. Let F(X, Y) denote the set of all function from X to Y. Is this set finite, countably infinite, or uncountable? Prove your answer
please explain it step by step( not use the example with number) thanks 1. Determine whether each of these sets is countable or uncountable. For those that are countably infinite, prove that the set is countably infinite. (a) integers not divisible by 3.

Suppose is a subset of the cartesian product of a finite set and uncountable set, anuBis the product two countably infinite sets.What can you say about|A∩B|? What can you say about|P(A∪B)|?
Prove that a disjoint union of any finite set and any countably infinite set is countably infinite. Proof: Suppose A is any finite set, B is any countably infinite set, and A and B are disjoint. By definition of disjoint, A ∩ B = ∅ Then h is one-to-one because f and g are one-to one and A ∩ B = 0. Further, h is onto because f and g are onto and given any element x in A ∪...
A large, commercial program will define one functions Select one: True False Function return-type specifies the type of data returned by the function. This can (int, double, array, float). Select one: True False
17-26 true or false questions 17. The smallest positive real number is c, where c = card(0,1). 18. To show that two sets A and B are equal, show that x A and x B. 19. If (vx)P(e) is false, then P(x) is never true for that domain. 20. If R is a relation on A and if (a, a) is true for some a in A, then R is reflexive. 21. If f:A → B is a function, then...
Determine whether each of these functions from the set of integers to the set of integers is injective, surjective, or bijective. f(x)=1+X^2 f(x)=2x f(x)=17+x
