Question 1167002
.


            Tutor   @solver91311 just gave you the correct answer.


            I also want to add my  2  cents.



<pre>
The condition  P(C|D) = 0.7  just tells you that the events C and D are not mutually exclusive.



     Otherwise,  P(C|D)  would be zero, by the definition of mutually exclusive events.



But, actually, this condition P(C|D) = 0.7 is EXCESSIVE.


Two conditions, P(C) = 0.5 and P(D) = 0.6  are just ENOUGH to conclude that the the events C and D are not mutually exclusive.



Indeed, otherwise it would be 


    P(C U D) = P(C) + P(D) = 0.5 + 0.6 = 1.1 > 1   (for mutually exclusive events, probabilities are added (!) )


which is IMPOSSIBLE.

So, &nbsp;again, &nbsp;having two conditions &nbsp;P(C) = 0.5 &nbsp;and &nbsp;P(D) = 0.6 &nbsp;is just enough to conclude 

that the events &nbsp;C &nbsp;and D &nbsp;&nbsp;ARE &nbsp;NOT &nbsp;mutually exclusive.
