Demonstrate that the definition of conditional probability Pr (A | B) = Pr (A, B) Pr (B) satisfies the three axioms of probability.

## Relevant Questions

Prove that if Pr (B | A), then it follows that (a) Pr (A, B) = Pr (A) Pr (B) and (b) Pr (A, B) = Pr (A). Furthermore, show that if, then the two conditions above do not hold as well. Consider two events A and B such that Pr (A)>Pr (B). Determine if Pr (A|B)>Pr (B|A) is always true, sometimes true, or never true. I deal myself 13 cards for a standard 52- card deck.
