A random experiment has an unpredictable outcome.
Examples include tossing a coin, playing the lottery,
driving a car, taking an exam......
Interpretations of Probability
- 1.
- Long term frequency,
as in the limit of the number
of 6's that appear in many tosses of a fair dice.
- 2.
- Measure of belief:
P(I survive surgical operation)
This experiment cannot be repeated, the only
interpretation would be that of a measure of
belief.
Beware:
Our first intuitive
ideas about probability can be fraught with
fallacies, in that they sometimes
do not obey the axioms they should.
