Bayes Theorem کا حساب کیسے لگائیں

Bayes Theorem کیا ہے؟

Applies Bayes theorem updating probability based on new evidence. Foundation of probabilistic reasoning.

فارمولا

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

مرحلہ وار گائیڈ

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

حل شدہ مثالیں

ان پٹ

نتیجہ
P(A|B) calculated

عام غلطیاں جن سے بچنا ہے

  • Confusing conditional probabilities
  • Not updating priors properly
  • Forgetting normalization constant P(B)

اکثر پوچھے جانے والے سوالات

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.
