Question

If A and B are independent events, which equation must be true?




AA.)P(B|A) = P(A)




B.)P(B|A) = P(B)




C.)P(B|A) = P(A) × P(B)




D.)P(B|A) = P(A) + P(B)

Answer 1

If the events A and B are independent then P(AB)=P(A)P(B)
Now P(B|A)=P(AB)/P(A)=P(A)P(B)/P(A)=P(B)

Answer 2

Hence 2 is satisfied @tiannataylor890
