Answer: All of the answers are correct.

Step-by-step explanation:

A probability distribution is the collection of probabilities which defines the likelihood of observing all the various outcomes of an experiment or event. A probability distribution has two main properties which are that:

• Each probability in the distribution consist of a value between 0 and 1.

• The sum of all probabilities in the distribution equals 1.

Also, in probability, an outcome is the possible result of an experiment and each possible outcome gotten is unique, therefore the different outcomes are mutually exclusive i. e. only one outcome can occur on each trial during the experiment.
