------------------------------------------
(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
