Applies Bayes theorem updating probability based on new evidence. Foundation of probabilistic reasoning.
ସୂତ୍ର
P(A|B) = P(B|A) × P(A) ÷ P(B)
- P
- overall probability of evidence — overall probability of evidence
- A
- likelihood of evidence given A — likelihood of evidence given A
- B
- overall probability of evidence — overall probability of evidence

- 1P(A|B) = P(B|A) × P(A) ÷ P(B)
- 2P(A|B) = posterior (updated probability)
- 3P(A) = prior probability
- 4P(B|A) = likelihood of evidence given A
- 5P(B) = overall probability of evidence

What's practical example?
Medical test: prior disease probability, test accuracy, posterior if positive test result.
Why is Bayes important?
Foundation of statistical inference, machine learning, and decision-making under uncertainty.
