Question 1197190
.
<pre>

(a)  P(A|B) = {{{P(A_and_B)/P(B)}}} = {{{0.56/0.8}}} = 0.7.    <U>ANSWER</U>


     P(B|A) = {{{P(A_and_B)/P(A)}}} = {{{0.56/0.7}}} = 0.8.    <U>ANSWER</U>



(b)  Events A and B are independent         <U>ANSWER</U>  

         because  P(A and B) = 0.56  is numerically the same as  P(A)*P(B) = 0.7*0.8 = 0.56.    
</pre>

Solved.
