7-3 Random Experiments, Sample Space and Events
Before we discuss the concept of probability, we need to introduce some
terms that we will encounter later in this chapter. We will explain the
concept of probability through these terminologies.
Random Experiment
When we randomly select an item from a production line, as mentioned
earlier, we do not know the outcome. Let us refer to this process of selecting
the item as an
experiment
. We will define such an experiment as a random
or probability experiment since we do not know the outcome in advance.
Definition: Random Experiment
A random experiment is an experiment in which the outcome on each
trial is unknown and distinct.
Examples of random experiments are everywhere around us. For instance,
the rolling of a regular six-sided die, the selection of numbers by a lottery
machine, which slot or compartment will the ball end up on a roulette wheel,
etc.
