## Axiom of Positivity, Certainity and Union

Axiomatic Approach Axiomatic approach is a way of describing probability of an event. If S is the sample space of a random experiment and E is the power set of S, then a real valued function from E to [0,1] […]

## What is Probability?

If S is the sample space of a random experiment, ‘E’ is any event, then probability of E is denoted by P(E) and is defined as P(E) = (Number of Simple Events in E / Total Number of Simple Events
