Question

What is the sum of all probability

Answer 1

The sum of the probabilities in a probability distribution is always 1.

A probability distribution is a collection of probabilities that defines the likelihood of observing all of the various outcomes of an event or experiment. Based on this definition, a probability distribution has two important properties that are always true:

Each probability in the distribution must be of a value between 0 and 1.The sum of all the probabilities in the distribution must be equal to 1.

An example: You could define a probability distribution for the observation for the number displayed by a single roll of a die. The probability that the die with show a "1" is 1/6.
