Sample space: When we perform an experiment ,then the set S of all possible outcome is called the sample space.eg of sample space: (i)in tossing a coin ,s={h,t} Event: Any subset of a sample space. Probability: Probability is quantitative measure of the chance of occurrence of a particular event..let S be the sample space and E be the event .then,E subset of S.then P(E)=n(E)/n(S). (i) P(S) = 1 (ii) 0<P(E)<1 If A denotes (not-a),then P(A)=1-P(A). Let A and B be two events associated with a random experiment. Then |
