<PRE><B>Question 1123190</B>
.
&lt;U&gt;Given&lt;/U&gt;

&lt;pre&gt;
In a class of 30 students,17 play football, 15 play volleyball, 12 play rugby, 
9 play only football, 
6 play only volleyball              &lt;&lt;&lt;---=== 
and 3 play only rugby. 
If all the pupils play at least one of the three games, 
&lt;/pre&gt;

&lt;U&gt;Find&lt;/U&gt;

&lt;pre&gt;
Find the number of students who play only volleyball 
and display in the information on a venn diagram
&lt;/pre&gt;


Above I placed what is given and what the problem is asking for.


&lt;pre&gt;
It asks &quot;&lt;U&gt;Find the number of students who play only volleyball&lt;/U&gt;&quot;.


The answer is exactly in the line of the condition which I marked as &quot; &lt;&lt;&lt;---=== &quot; .
I repeat it here again: 

          &quot;6 play only volleyball&quot;.
&lt;/pre&gt;

Did I answered the major question ?
