CHAPTER 15 Probability Probabilty Experiment Random Event Outcomes experiment Equally likely Sample Experimental Complementary space probability event Sure event Impossible Favourable event outcomes Theoritical or classical probabilty KEY POINTS: 1. Probability is a quantitative measure of likelihood of occurrence of an event. Number of outcomes favourable to E 2. Probability of an event E= Total number of outcomes 3. 0  P (E)  1 4. If P(E) = 0, then it is an impossible event. 5. If P(E) = 1, then it is sure event. 6. If E is an event, then not E( E ) is called complementary event. 7. P( E ) = 1 – P(E)  P(E) + P( E ) = 1 8. Probability of an event is never negative. 9. Sample space (S) : The collection of all possible outcomes of an event. Mathematics-X 229
