Question

For independent events, which equality holds provided \[P(B)\neq 0\]?

Options

• \[P(A\mid B)=P(B)\]

• \[P(A\mid B)=P(A)\]

• \[P(A\mid B)=1-P(A)\]

• \[P(A\mid B)=P(A\cap B)\]

Answer 1

For independent events, knowing that B occurred does not change the probability of A. Thus the conditional probability remains \[P(A)\].
