Artificial Intelligence / Unit 6 AI 0295 short lesson, about 20 seconds
Probability Is Degree of Belief
Captions available
The idea
A probability is a number between 0 and 1 measuring an agent's degree of belief that a claim is true — 0 certainly false, 1 certainly true.
In practice
Belief 0.7 that the van has left: the van is parked or gone, fully — the 0.7 measures the believer's ignorance.
Where people slip
A middle value never means partly true — the agent does not know which truth holds.
