Introduction to Probability Onur DOĞAN
Introduction to Probability • The Classical Interpretation of Probability • The Frequency Interpretation of Probability • The Subjective Interpretation of Probability
Types of Experiments Experiment and Event: An experiment is anyprocess, real or hypothetical, in whichthe possible outcomes can be identified ahead of time. An event is a well-defined setof possible outcomes of the experiment.
Sample Space The collection of all possible outcomes of an experiment is called thesample space of the experiment. A: Event S: Collection of all events
The Empty Set Some events are impossible. For example, when a die is rolled, it • is impossible to obtain a negative number. Hence, the event that a negative number • will be obtained is defined by the subset of S that contains no outcomes.
Operations of Set Theory • Intersection and union operations have associativeand distributive properties . • De Morgan’s Law
AxiomsandBasicTheorems • Axiom(1) / Axiom(2) / Axiom(3) • Further Properties of Probability:
Permutations • Obtaining Different Numbers:
