Define an 'event'.

Elementary an outcome of a random experiment is called an elementary event.

Favourable elementary event an elementary event is said to be favourable to a compound event A if it satisfies the definition of the compound.

Definition if there are n elementary events associated with a random experiment and m of them are favourable to an event A then the probability of happening or occurrence of event A is denoted by P(A) and is defined as the ratio (m)/(n) .

Define a event.

P(barA)=(Favourable number of elementary events to event bar A) / (Total number of elementary events).
