Which of the following describes a ratio of actual events to the number of trials in an experiment? Select all that apply.

prediction

experimental probability

theoretical probability

relative frequency

trial

uniform probability model

A uniform probability model would best likely be used when describing a ratio of actual events to the number of trials in an experiment. By definition, this probability model also called as "rectangular distribution model" is used when all the factors involving in the study are "equally probable."

And experimental probability and relative frequency.
