alleryBayes' theorem is primarily used to
Afind $P(A\cup B)$ from $P(A)$ and $P(B)$ only
Bcompute variance of a random variable
Crevise the probability of a cause after observing an event
Dtest whether a sample space is discrete
Answer & Solution
Correct answer: C. revise the probability of a cause after observing an event
Bayes' theorem updates the probability of a hypothesis or cause after evidence is observed.
It converts a probability like $P(A/E)$ into one involving $P(E/A)$ and the total probability of the evidence.
