Consider event A and event B. What is the probability that event B occurs, given that event A has already occurred?

P(B A)
P(A) ∙ P(B)


P(B A)
P(A)


P(B A)
P(B)


P(B A)
P(B)

P(B|A) = P(B), based on your description, it does not indicate any relationship between A and B, so P(B) is irrelevant with P(A)

Answer:

P(B A)=P(B)

Step-by-step explanation:

Given situation that two events occurred event A and event B

event A has already occurred

therefore, there is no relationship between them event A and event B

since, the probability of B does not depend on any activity of A

therefore, P(B A)=P(B)
