Introduction:
In everyday life, we come across the situations having either some
certainty or uncertainty and we are generally interested to
measure this certainty or uncertainty. We want to measure that up
to what extent this particular situation would occur. We generally
achieve it qualitatively; not able to calculate it quantitatively. So
what about if we want to measure it quantitatively? That is
achieved with the help of the Theory of Probability.
What is Probability?
Qualitatively:
Probability is the Measure of Uncertainty.
Quantitatively:
To measure the probability quantitatively, we have to take certain
steps associated with the given situation to collect some input so
as to produce the quantitative value of the probability.
To define the probability quantitatively associated with the
given situation, first we perform a RANDOM EXPERIMENT.
First let us know what does it mean by EXPERIMENT in
probability theory.
Suppose we want to find out the temperature of a room. We
put a thermometer in the room for some time. After some
