The sum of the probabilities of all the elementary elements of an experiment will be 1.
The basic theory of probability states that the the sum of the probabilities of a certain or sure event shall be 1 ,as all the events should have nearly the same chances of occurring.
Thus, the sum of their respective probabilities should be 1 as it is a sure event.
The answer to this question will be 1.
