Complete the following statements: (i) Probability of an event E + Probability of the event 'not E' =__. (ii) The probability of an event that cannot happen is___ Such an event is called__ (iii) The probability of an event that is certain to happen is__. Such an event is called__. (iv) The sum of the probabilities of all the elementary events of an experiment is (v) The probability of an event is greater than or equal to __ and less than or equal to__

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

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

Compound event an event associated to a random experiment is a compound event if it is obtained by combining two or more elementary events associated to the random experiment.
