Are mutually exclusive events are always independent?

$begingroup$


I have a confusion between independent events and mutually exclusive events.




  • independent events is defined in terms of



probability of events
while mutually exclusive is defined in terms of events (subset of sample space)





  • mutually exclusive events never have a common outcome but probability of events may have a common outcome.
    All i understand they donot have same meaning.
    So can i conclude that mutually exclusive events are independent while independent events may or may not be mutually exclusive events?

    Mutually exclusive events are never independent since knowing one occurred gives you knowledge that the other event didn't occur

    @Mark so independent terms having non zero probabilities are also not mutually exclusive.

    Yes you can see that by $P(A cap B) = P(A)P(B) > 0$ showing that there is some probability both occur

    @Mark was i am wrong in telling that independent terms may have a common outcome? ie should it be independent terms always have a common outcome.
