<PRE><B>Question 140064</B>
The total different outcomes of the two spinners are
4* 4= 16
The outcomes are (10,1),(10,2),(10,3),(10,4),(12,1),(12,2),(12,3),(12,4),(14,1),
(14,2),(14,2),(14,3),(18,1),(18,2),(18,3),(18,4)


Out of these pairs, the ones for which the difference is multiple of 3 are:
(10,1), difference 9
(10,4)  difference 6
(12,3)  difference 9
(14,2)  difference 12
(18,3)  difference 15

So the required probability = favorable outcomes/ total outcome
                            = 5/16</PRE>
