What does the term 'probability' mean?
A measure of how likely an event is to occur, expressed as a number between 0 (impossible) and 1 (certain).
The likelihood of an event happening, usually expressed as a percentage.
A statistical measure of the average outcome of an event.
The certainty that an event will not occur.
What is the likelihood scale?
A way to measure temperature
A method for categorizing events as impossible, unlikely, likely, very likely, and certain
A scale used for measuring distances
A technique for assessing financial risks
What does it mean if an event is described as 'unlikely'?
It means that the event has a high probability of occurring, typically more than 50%.
It means that the event has a low probability of occurring, typically less than 50%.
It means that the event is certain to happen.
It means that the event is impossible to happen.
What probability percentage is considered 'very likely'?
50% or higher
70% or higher

What probability percentage is considered 'likely'?

How can we express the likelihood of an event that is certain?
As a probability of 50%
