Axioms are: -(adsbygoogle = window.adsbygoogle || []).push({});

1) P(E) >= 0

2) P(S) = 1

3) P(E_{1}U E_{2}U ...) = P(E1) + P(E2) + .... if all are mutually exclusive

Why are the axioms defined in such a way? Why not this simple axiom: - Probability of an event is number of favorable outcomes divided by total number of outcomes?
