Prove that each of the following pairs of sets have the same cardinality. (a) We have the sets X and Y, where X is the set of even positive integers and Y is the set containing all those positive integers that yield. A remainder of 2 when divided by 3. Prove that the each of the following pairs of sets have the same cardinality. (b) We have the sets X and Y X = Y = {a ER: x= 1/n for some n E N} = {1,,,,...} {a e R: a = 1/(n+1) for some n E N} = {...} (c) The intervals [0, 1] and [0, 1) as subsets of R. Use the following step to prove (1)Make a function that you claim is a bijection between the two sets. (2) Proof of your function maps entire domain into its codomain. (3) Prove of your function is an injection (4) Prove of your function is a surjection.
