How likely you think something is to happen depends on what you already believe about the circumstances. That is the simple ...

Conditional Probability: The probability of an event occurring given that another event has already occurred, fundamental to statistical inference and decision-making processes.

Explain why probability is important to statistics and data science. See the relationship between conditional and independent events in a statistical experiment. Calculate the expectation and variance ...

The quotient rule is often spoken of as a definition of conditional probability in terms of unconditional ones -- when the unconditional probability of the condition D is positive.

Prior probability, in Bayesian statistical inference, is the probability of an event based on established knowledge, before empirical data is collected.
