Equally likely outcomes
Equally likely outcomes are outcomes that have the same chance of happening in an experiment.
Practice This ConceptMain explanation
Teacher explanation
This idea is very important because the basic probability formula works properly only when outcomes are equally likely. A fair coin has H and T with the same chance, and a fair die has 1 to 6 with the same chance. If the object is biased, the simple formula may not be valid in the same direct way.
Example
In a fair die throw, each face from 1 to 6 has the same chance, so the outcomes are equally likely.
Simple analogy
Same chance means equally likely.
Common confusion
Students sometimes call outcomes equally likely just because there are many outcomes, even when the object is biased.
Exam tip
Always ask first: is the coin, die, or spinner fair before applying the counting formula?
