STATISTICS (M)

1) SOME BASIC TERMS AND CONCEPTS    a) An Experiment: An action or operation resulting in two or more outcomes is called an experiment.      b) Sample Space: The set of all possible possible all possible possible outcomes of an experiment is experiment is called the sample space, denoted by S. An element of S is called sample point.   c) Event : Any subset of sample space is an event.   d) Simple Event: An event is called simple event if it is a singleton subset of subset of sample space S.   e) Compound Events: It is the joint occurrence of two or more simple events.   f) Equally Likely Events: A number of simple events are said to be equally likely if there is no reason for one event to occur to occur occur in preference to any other event.   g) Exhaustive Events: All the possible outcomes taken together in which an experiment can result as said to be exhaustive or disjoint.   h) Mutually Exclusive or Disjoint Events: If two events cannot occur simultaneously, then they are mutually
