Basic Probability 1.1 Basic De nitions Trials? Probability is concerned with the outcome of tri-als.? Trials are also called experiments or observa-tions (multiple trials).? Trials refers to an event whose outcome is un-known. Sample Space (S)? Set of all possible elementary outcomes of a trial.? If the trial consists of ipping a coin twice, the Statistical data are the basic raw material of statistics. Data may relate to an activity of our interest, a phenomenon, or a problem situation under study. They derive as a result of the process of measuring, counting and/or observing. Statistical data, therefore, refer to those aspects of a problem situation that can be measured,
