What is the sum of the probabilities in a probability distribution?

Expert Solution

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.

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