<PRE><B>Question 216271</B>
 A Teacher asked her class to raise their hand if they liked carrots. 11 students raised their hands. There were 9 students who raised their hands liking spinach. There were 7 students who did not like either of the vegetables. All 24 students in the class voted. how many students liked both carrots and spinach?
------------------------------------------
(carrots and spinach) = (carrots)+(spinach)-(carrots or spinach)
carrots and spinach) = 11 + 9 - (24-7)
(carrots and spinach) = 20-14 = 6
-------------------------------
6 students liked both carrots and spinach
-------------------------------
You can see all this if you can draw a Venn diagram
