Best ResponseYou've already chosen the best response.0Yeah if event a is independent of event b, then the relation you gave is valid.

Best ResponseYou've already chosen the best response.0if i do it my self i get .87098=(.12)(.067) IS THIS RIGHT?

Best ResponseYou've already chosen the best response.0perhaps the question asks "are the events independent?" Since P(a) is not equal P(ab) they are not independent. Or perhaps you are being asked for P(a intersect b) which you get by multiplying P(ab)*p(b) = .870968*.067

Best ResponseYou've already chosen the best response.0Yeah, I think what satelliet said is true; the question is asking to show weather a and b are independent events or not.

Best ResponseYou've already chosen the best response.0We have the following formula for P(ab)=P(a n b)/P(b). We now will see if this relation is still valid when substituting P(a n b)=P(a)P(b). If this is the case, then they are independent. If not, then they are dependent.
