(a) Prove directly that the cardinality of the closed interval [0, 1] is equal to the cardinality of the open interval (0, 1) by constructing a function f : [0, 1] → (0, 1) that is one-to-one and onto. (b) More generally, show that if S is an infinite set and {a,b} C S, then [S] = |S \ {a,b}\. (The notation S \ {a,b} is used to denote the set of all s in S such that s is...

.1. Write a Python script for compute P50 k=1 P100 j=−2 (k − 2j) 2. It is clear that the cardinality of the Natural numbers is no more than the cardinality of the Rational numbers. Show that Rational numbers have cardinality no greater than the natural numbers (and therefore they have the same cardinality). 3. Prove (by contradiction) that the real numbers are uncountable.
