On the other hand
We
use the language of probability to talk about how much we believe something may come to pass or how much we believe it's true.
Um
This is known as credence, like creed belief, credence probability.
Um some people call it Bayesian probability, named after uh Bayes um
Who yeah.
centuries ago worked on on the structure of probability and developed a framework that people who use probability in this credence sense use to try to
formulate statements about what they think is gonna happen in the world.
So you have these two different notions of probability.
Um and
When you have a physical theory
That
describes processes by which phenomena take place and the physical theory is not able to tell you definitively exactly what outcome will happen.
Often these physical theories will tell you that what you'll expect to see is a pattern of phenomena.
And this pattern of phenomena will be random looking, but maybe with some bias toward one thing or another.
And so we say that this is a a theory, a physical theory that's describing chance probabilities in some sense.
If you have a theory like Everettian quantum mechanics, and Everett in quantum mechanics is not unique in this regard, um, in which the overall picture
Provided by the theory is that the overall process is deterministic.
There's no fundamental probabilities, no chance probabilities really happening.
