Best ResponseYou've already chosen the best response.1If two events are mutually exclusive, then the probability of one event does NOT depend on the other occurring (or not occurring). ie P(B I A)=P(B) and P(A  B)=P(A)

Best ResponseYou've already chosen the best response.1Have a look at the probability values they gave you. P(B I A)=0.4 and P(B)=0.3 Now compare them to this... P(B I A)=P(B) which is true for mutually exclusive events.
