alleryStart learning →Bayes's rule allows you to compute
AP(A | B) from P(B | A), P(A), and P(B)
BMarginal distribution from a joint
CVariance from expectation alone
DIndependence from correlation
Answer & Solution
Correct answer: A. P(A | B) from P(B | A), P(A), and P(B)
**Bayes's rule:** P(A | B) = P(B | A) · P(A) / P(B).
Central to probabilistic ML — converts a likelihood + prior into a posterior.
