CHAPTER 15
PROBABILITY

(i) Probability
(ii) Miscellaneous Questions

1. The Theoretical probability of the occurence of an event E written as P(E) is P(E)=$\frac{{Number\;of\; outcomes \;favourable \;of\; E}} {{Number \;of \;all\; possible\; outcomes \;of \;the \;experiment}}$
2. Experiment: An activity which ends in some well defined outcomes is called an experiment.
3. Trial: Performing an experiment once is called a trial.
4. Event: The possible outcomes of a trial is called an event.
5. Sure event: An event whose occurence is certain is called a sure event.
6. The sum of the probability of all the elementary events of an experiment is 1.
7. The probability of a sure event is 1 and probability of an impossible event is 0.
8. If E is an event, in general, it is true that ${\text{P}}\left( {\text{E}} \right){\text{ }} + {\text{ P }}\left( {\overline {{\text{E }}} } \right){\text{ }} = {\text{ 1}}.$   $[ P(\overline E) = P(not E) ]$
9. From the definition of the probability, the numerator is always less than or equal to the denominator therefore $0 \le P(E) \le 1$.
