- We find the probability of the occurrence of an event by actually performing the experiment a number of times and adequate recording of the happening of event.
- An Outcome of a random experiment is called an elementary event.
- Probability of an event E, written as P(E), is defined as [latex]P(E)=\frac { Number\quad of\quad outcomes\quad favourable\quad to\quad E }{ Number\quad of\quad all\quad possible\quad outcomes\quad of\quad the\quad experiment } [/latex]
- An event associated to random experiment is a compound event if it is obtained by combining two or more elementary events associated to the random experiment.
