.


<U>HINT</U>.  &nbsp;&nbsp;Since the events &nbsp;"a" &nbsp;and &nbsp;"b" &nbsp;are mutually exclusive, &nbsp;they can not occur both simultaneously.



<pre>
    Therefore, &nbsp;the answer to &nbsp;(a) &nbsp;is  &nbsp;&nbsp;P = 1 - P(A) - P(B) = 1 - 0.14 - 0.56 = 0.3.


    The answer to &nbsp;(b) &nbsp;is  &nbsp;&nbsp;P = P(B) = 0.56.
