Question

A and B are two events.The notation for conditional probability is P(B|A). Which notation is the probability of two events being not independent? Responses P(B|A)=P(B) P left parenthesis B vertical line A right parenthesis equals P left parenthesis B right parenthesis P(B|A)=P(A)P(B) P left parenthesis B vertical line A right parenthesis equals fraction begin numerator P left parenthesis A right parenthesis end numerator over P left parenthesis B right parenthesis end fraction P(B|A)=P(B)P(A) P left parenthesis B vertical line A right parenthesis equals fraction begin numerator P left parenthesis B right parenthesis end numerator over P left parenthesis A right parenthesis end fraction P(B|A)=P(A and B)P(A)

Answer 1

The notation for the probability of two events not being independent is P(B|A) = P(A and B) / P(A). This equation represents the conditional probability of event B occurring given that event A has already occurred. It allows us to calculate the probability of event B happening, taking into account the occurrence of event A.
