    Axioms of probability and sigma additivity

    The third axiom of probability states that given an infinite sequence of mutually exclusive events A1, A2, .... we have P(A1 U A2 U ...) = P(A1) + P(A2) + ... (The probability of their union is equal to the sum of their probabilities) So take the following problem. I have a positive integer in...
