## Definition: Random Experiments and Random Events

A random experiment is an experiment with the following properties:

• It is known, which outcomes it has, before it takes place, but
• is is generally unknown, which outcome it will have, until the experiment took place, and
• it is possible to find out, which outcome the experiment had after it took place.

The set of all outcomes is called probability space and denoted by $$\Omega$$.

Any subset $$F\subseteq \Omega$$ of outcomes is called a random event or just event. We denote events, using Latin capital letters $$A,B,C,\ldots$$.
