Question: Problem 2.15 Let B denote an event for which P(B) > 0. Define a set function P via the recipe P (A) = P(A

Problem 2.15 Let B denote an event for which P(B) > 0. Define a set function P via the recipe P (A) = P(A ∩ B) P(B) . Show that P satisfies the axioms for a probability measure. P (A) is called “the conditional probability of A given that B has occurred.” Section 2.3: Discrete sample spaces, permutations, combinations, and binomial coefficients
