Definition
Equally likely outcomes
Outcomes that each have the same probability in the stated chance model.
What it means
Compare the chances, not just what happened in a few trials. If no listed outcome has a bigger probability than another, those outcomes are equally likely in that model.
Remember it
Same model, same chance for every compared outcome.
Example
A fair four-section spinner has one star, one moon, one leaf, and one wave on equal sections. Each outcome has probability 1/4, so the four outcomes are equally likely.
Watch for
Two named outcomes are not automatically equally likely. On a spinner with three red sections and one blue section, red and blue do not have equal chances.
Common mix-up
Equal numbers of outcome names do not prove equal likelihood; the model must assign the same probability to each outcome.
Exact meaning
Outcomes are equally likely when a probability model assigns the same probability to each outcome being compared.
