Aand b are two events. which statement about the conditional probability is true?
a. the conditional probability of event b given event a is p(b|a)=p(a and b)/p(a) when two events are not independent.
b. the conditional probability of event b given event a is p(b|a)=p(b) when two events are not independent.
c. the conditional probability of event b given event a is p(b|a)=p(b)/p(a) when two events are independent.
d. the conditional probability of event b given event a is p(b|a)=p(a)/p(b) when two events are independent.
