Problem 8.43. For sake of a contradiction, assume the interval (0,1) is countable. Then there exists a bijection f : N-> (0,1). For each n є N, its image under f is some number in (0, 1). Let f(n) :-0.aina2na3n , where ain 1s the first digit in the decimal form for the image of n, a2 is the second digit, and so on. If f (n) terminates after k digits, then our convention will be...

2. (32%) Short answer questions. Decide for each of the following statements if they are true or false, and give a short explanation. You may use all the theorems on "The Sheet." (a) The set {fonim, neN} is countable. (b) Every subset of an uncountable set is uncountable. (c) Suppose f:R-R is a function. For any two subsets AcR and BCR one has f(An B) = f(A) n (B). (d) If an and by are sequences of positive real numbers,...

Identify the correct steps involved in proving that the union of a countable number of countable sets is countable. (Check all that apply.) Check All That Apply Since empty sets do not contribute any elements to unions, we can assume that none of the sets in our given countable collection of countable sets is an empty set. If there are no sets in the collection, then the union is empty and therefore countable, Otherwise let the countable sets be As,...
