Question

the sum of the probabilities of all the elementary events of an experiment is __​

Answer 1

Question:-

the sum of the probabilities of all the elementary events of an experiment is ?

Answer:-

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.

Answer 2

Step-by-step explanation:

(iv) The sum of the probabilities of all the elementary events of an experiment is 1. (v) The probability of an event is greater than or equal to 0 and less than or equal to 1.
