Answer:
none of these
Step-by-step explanation:
The sum of the probabilities of all outcomes must equal 1 . If two events have no outcomes in common, the probability that one or the other occurs is the sum of their individual probabilities. The probability that an event does not occur is 1 minus the probability that the event does occur.

Answer:
elementary
The probability p of any event must be greater than or equal to 0.
In other words, 0≤p≤1.
Since 1 is the maximum limit, all probabilities must add to 1.
Hence, the sum of the probabilities of all the elementary events of an experiment is 1.
