Question 1140032
.
<pre>

You are given 

    P(Y) = 0.3                    for yellow

    P(G) = 0.1                    for green

    P(B) = 0.6 (= 1 - 0.3 - 0.1)  for blue.


(A)  P = P(Y)*P(Y) + P(G)*P(G) + P(B)*P(B) = {{{0.3^2 + 0.1^2 + 0.6^2}}} = 0.46.     <U>ANSWER</U>


(B)  This probability is the probability to point to  

             (Y,G) or (G,Y);  

         or  (Y,B) or (B,Y);   

         or  (Y,Y), 


      and is equal thus to  2*0.3*0.1 + 2*0.3*0.6 + 0.3*0.3 = 0.51.    <U>ANSWER</U>
