You can put this solution on YOUR website! 50 students were given a survey on jellybeans. 30 like red, 29 like green and 17 like both red and green.
------------------------------------
Draw a Venn diagram.
Draw two overlappiing circles inside a rectangle.
Lable one circle "red", the other "green".
put 17 in the intersection of the circles.
---
put 30-17 = 13 in the red circle but not in the intersection.
---
put 29-17 = 12 in the green circle but not in the intersection.
---
How many of the students like neither red or green?
Total # in the rectangle is 50.
Total # in the two circles is 13 + 17 + 12 = 42
------
So, total # in the rectangle and not in the circles is 8.
