7. The sum of probabilities of all elementary events of an experiment is equal to​

Answer 1

Answer:

7 =1

Step-by-step explanation:

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.
